Huang X., Zhang L., wang X., Wu D., 2016, Determination of the Reaction Rate Constant for the Opposing Reaction by Integral Method, Chemical Engineering Transactions, 55, 19-24.
In order to calculate the forward reaction rate constant and the reverse reaction rate constant of the opposing reaction, a calculation program was designed with VB language. According to the law of mass action, the reaction rate equation was established and it was converted into integral expression, the experimental data are calculated by using variable step size trapezoidal quadrature and least square method. The accuracy of the program in numerical simulation was verified by an example; the results show that the calculated values are in good agreement with the literature values. Inputting different parameters, the program can calculate the reaction rate of different types of the opposing reaction. It is convenient, quick and accurate to calculate the rate constant of the opposing reaction by the program. The program can be used as a tool in studying the opposing reaction.
