This study aims to develop mathematical models of the non-isothermal CSTR for the alkaline hydrolysis of methyl ethanoate, making use of both the theoretical and experimental approach. It includes the determination of the kinetics of the said reaction, as well as the determination of the thermodynamic properties such as heat of reaction and activation energy.For the development of the theoretical models, material and energy balances are performed around the system, and the resulting system of differential equations is solved simultaneously by the fourth order Runge-Kutta method. For the experimental approach, a discrete-time model is developed making use of an assumed linear difference equation and solving for the parameters which give the best fit. The kinetics of the reaction is determined by the volumetric analysis of the samples. Experimental data are obtained by taking samples from the CSTR every two minutes. Temperature readings are also taken every two minutes. These values are plotted versus time and the graphs compared with those generated from the theoretical model.A computer program to solve the differential equations by Runge-Kutta is written in Turbo Pascal.
