Sodium hydrated oxide and ethyl ethanoate are two reactants known to bring forth sodium ethanoate and ethyl intoxicant when used with ceaseless stirred armored combat vehicle reactor that is why they have been used in this experiment to cipher reaction rate invariables and out the activation energy. Different temperatures i.e. 293 K, 303 K and 313 K in that order was applied to the experiment each clip to find the values of conduction through it. It was observed that when the concentration of Na hydrated oxide decreased and of the ethyl ethanoate increased it will give lower values of conduction. So, we can infer that as a consequence of this experiment an reverse proportional relationship between the Na hydrated oxide and ethyl ethanoate concentrations and the values of the temperatures is formed. In add-on to this, the value of the activation energy can be determined through analyzing the association between the natural logarithm for the reaction rate invariables and the reverse temperature of the reactants.


The cardinal aims of this experiment involve ciphering the reaction rate invariables and to grok the procedure that leads to different reaction rate invariables at different values of temperatures when applied to a reaction. These aims are achieved by utilizing the uninterrupted stirred armored combat vehicle reactor for the liquid stage.

The theory of cardinal importance to the field of technology ; homogeneous reactions conducted in a uninterrupted moved armored combat vehicle reactor has been explored here in this study. Since it is known that that the clip is responsible for the creative activity of conductive characteristics of a substance three changing values of temperatures were applied to this reaction to analyze the relationship between the applied temperatures and the attendant conduction. The Arrhenius equation suggests that the reaction rate invariables helped in mensurating the values of activation energy at merely two temperatures therefore the values of the activation energy defines the energy needed for the reaction to take topographic point.

Furthermore, the impacts of reactants, the concentration of the reactants, and the concentration of the merchandises and merchandises on the conduction will besides be studied in this study. The reactants i.e. Na hydrated oxide and ethyl ethanoate possess the indispensable degree of energy to respond as deduced from the negative values of the activation energy.

Literature Review

The chemical reactor can be bifurcated into two subdivisions i.e. a armored combat vehicle reactor and a cannular reactor. The armored combat vehicle reactor has the capableness to brace the temperature in the mixture and the concentration both. It is due to this belongings that it is deemed so valuable because any chemical procedure can non be performed without a chemical reactor. However, when carry oning a chemical reaction in uninterrupted and fluxing system a cannular reactor is used to depict because of its capableness to cipher the features of the chemical reactors.

The quality and the measure of the merchandises are used to find what type of reactors is needed for a specific industrial operation consider, batch procedure and uninterrupted procedure as an illustration as they are widely used in chemical reactions. And industrial procedure is dependent on the cchemical reactions to a great extent. The batch reactors are expensive than uninterrupted stirred armored combat vehicle reactor but can non be operated at steady province. On the other manus, the uninterrupted stirred armored combat vehicle reactor is applicable to larger productions when the bbatch reactor is competent to be applied to smaller productions like the polymers.

A temperature accountant, baffle, chilling jacket, alligator and motor connected to package to salvage and pull off the values of the conductions are the basic constituents of the uninterrupted stirred armored combat vehicle reactor. This reactant is really effectual when different uninterrupted merchandises are needed.

Some reactions like the rusting of Fe are known as fast slow reactions as they take a period of old ages whereas slow reactions like the combustion of methane in O can take topographic point in takes seconds. The velocity of the reaction is used to mention to the reaction rate.

The reaction rate changeless can impact the temperature for illustration the kinetic energy of the atoms is high at high temperature which creates high degree of hit between these atoms finally increasing the reaction rate invariable.

The initial energy known as the activation energy it is produced even before the reaction is launched. The reaction rate invariables can mensurate the velocity of the reaction and is responsible for the activation energy besides. For get downing the reaction the molecules of the reaction must hold equal or higher energy. The unit used to denote it is J mol-1.

To rush the reaction up the activation energy demands to be minimized by adding substances to it. These additives- substances are known as the accelerator. These reaction accelerators are applied to diminish the activation energy and increase the reaction rate invariable. However, the accelerators have been basically designed to rush up the reaction while maintaining the reactants and the merchandises changeless.


When the reaction was launched five batches of 0.1mol dm-3 Na hydrated oxide and ethyl ethanoate were made ready. After which the coverings of the vass were detached from the surfaces and both the vass were filled with 50 millimeters every bit from the top and the temperature was set to be 293 K. The first vas contained sodium hydrated oxide whereas the 2nd vas contained ethyl ethanoate. To besiege the opportunities of harm or hurt in the class of carry oning this experiment everything was done in a unafraid manner and safeguards were taken that include ; have oning pprotective apparels, baseball mitts and safety spectacless. This experiment was done a sum of three times at different temperatures with the temperature being 303 K and 313 K for the 2nd and 3rd reaction. The standardization graph was used in the experiment through which the flow was fed into the reactor at 40 cm-3 min-1 by seting the pump. Subsequently on the fomenter velocity accountant was set to be 7.0 and the pump and the fomenter motor were switched on. They were linked to the informations lumberman plan which collected the information for 45 proceedingss so that a steady province transition could be achieved.


The experiment was conducted into a sum of three stages. In the first stage the temperature was set to be 293 K. this stage was carried out by a batch procedure at different times between 0s to 1320s. The 2nd stage the temperature was 303 K and the temperature in the 3rd stage was set to be 313 K whereas the type of the procedure was uninterrupted at a scope of clip between 0s to 2160s for both the stages. The measurings were besides taken at these two scopes of clip therefore the uninterrupted reaction ‘s equations were achieved. Through Table 1 we can see that the values of ?ao and ?? will increase at high temperatures. The Equation 5 and 6 show that the temperature is a map of ?ao and ?? and a direct proportional relationship between the values of ?ao and ?? and the temperatures exists.

The values of the conduction addition when the values of the temperatures addition. This is shown in Table 3 and 4. The conduction and the values of the temperatures are straight related because of lessening in the concentration of the Na hydrated oxide. The cations carry a positive charge and the anions carry a negative charge and the volume of dissociated ions is characterized by the values of the conduction. When there are equal dissociated ions of the reactants and of the merchandises the conduction tends towards stableness making a province known as equilibrium. In the province of equilibrium the reaction rate of the reactants to make merchandises similar to the reaction rate of the merchandises that yield the reactants.

The inversely relative relation between the conduction and clip is because of the higher concentration of Na hydroxide concentration we can besides state that the positive and negative ions i.e. cations and anions in that order were responsible for the lessening. When the figure of ions in the solution is decreased the lessening in the values of the conduction takes topographic point excessively. The ions occur because the solution has the ability to behavior.

When the supply of ethyl ethanoate is stopped the conduction will increase or we can besides state that sodium hydrated oxide happens to be strong bases that are ionized in H2O. The ions of a weak base are weak therefore conductivity is non possible. As a consequence of interaction between ions and other constituents a weak base will take topographic point. When the supply of ethyl ethanoate is stopped there will still be in the solution increasing the conduction. Nevertheless, when the supply of Na hydrated oxide is stopped in line for to the lessening in the Na hydrated oxide concentration in the armored combat vehicle the conduction will besides diminish.

There is an inversely relative relation between the values of the Na hydrated oxide concentration and the clip as shown in Table 3 and 4. This is because Na hydrated oxide produces more merchandises by its ability of interacting more. Furthermore, the concentration of Na ethanoate additions when clip increases because of production of Na ethanoate it was besides seen that the values of temperatures increase when the concentration of Na hydrated oxide decreases. This belongings is because the concentration of Na ethanoate additions with increasing values of temperatures. Likewise, when the rate of the transition from the reactants to the merchandises increases the temperatures besides increases. Therefore produced reaction is known as endothermal reaction. Furthermore, the reaction rate of the reaction depends on the addition in temperatures.

During an endothermal reaction, the addition in heat will take to the addition in the rate of the transition. Same is the instance with an exothermal reaction. The reaction given above shows that the reaction is endothermal as the addition in heat creates a lessening in the merchandises. However, when Na ethanoate is used the reactant known as Na hydrated oxide additions. Furthermore, the temperature increased when Na concentration was decreased On the other manus, addition in the values of the temperature increases the concentration of Na acetate the attendant alteration in values of the temperature will act upon the reaction.

The activation energy is achieved when the value of the gradient is multiplied by the cosmopolitan gas invariable ( 8.314 ) . It is shown in Figure 2 that there is an reverse relationship between the temperature and ln ( K ) . The relationship can be illustrated with the aid of a consecutive line which has a gradient used to get the activation energy.

An dissolution in clip of entering the measurings and the inaccurate values of the conduction ( these values were calculated in really little country of the reactor ) created a figure of mistakes during the experiment.


The values of the temperature, Na hydrated oxide and Na ethanoate concentrations are straight related to each other.

The values of the temperature and the Na hydrated oxide concentration have an opposite relationship. The ground for this relation is that the reaction is endothermal and the values of the temperature addition making an addition in the concentration of Na ethanoate.

At a peculiar clip and temperature the transition of Na hydrated oxide and Na ethanoate become the same.

The activation energy ever outputs positive values.

The conduction will diminish when the supply of NaOH is stopped nevertheless halting the supply of CH3COONa will ensue in higher conduction because a reaction takes topographic point between NaOH and CH3COONa. This reaction produces higher conduction and more solution because of the presence of strong ions.

At changeless values of conduction the stableness of the reaction will increase making a state of affairs known equilibrium.
