THEORY

EXPERIMENT A

The equipment of continuous stirred tank reactor (CSTR) has the ability to mix the liquid fairly and

completely with varies properties and temperature. CSTR perform a uniformity in reaction mixture

thoroughly in the tank respected to temperature and concentration. Sodium hydroxide and ethyl

acetate introduce in the tank at room temperature and constant throughout the mixing process.

Therefore the chemical equation:

NaOH + HCOOCH CHCOONa + CHOH

Sodium Hydroxide + Ethyl Acetate Sodium Acetate + Ethyl Alcohol

Both sodium hydroxide and ethyl acetate are 0.1M and 1.25L to make up to 2.5L mixture. The stirrer

used to mix the mixture after the mixture has reached 2.5L. The stirring process constant to the end of

experiment. Sodium hydroxide and ethyl acetate mixed to produce sodium acetate and ethyl alcohol.

The condition will eventually reach steady state when a certain amount of conversion of the starting

reagents has taken place. The steady state is reached depending on the concentration, flow rate,

volume of reactor and temperature of the system. The steady state is achieved once the reaction is

done and stable. For every five minutes, the sample has been taken out for the titration process with

HCL

Experiment B will involve in the increment of temperature from room temperature to 40C. Heat has

been introduced to the experiment to find out the effect and its consequences to the reaction. Factually,

heat will eventually transfer its energy to the particles in the reaction and therefore the particles will

move freely even faster and collide more frequently compare to room temperature. The higher the

temperature, the collisions will be more violent and the velocity also increase. The reaction will end up

more effective since heat can speed up the reaction with the kinetic energy. The rate of reaction is

roughly doubled with every 10K increment.

Rate of reaction is calculated manually with using the formula of:
