Estimation of Kinetic Parameters for Non-Elementary Reactions by Linear Regression

1 Estimation of Kinetic Parameters for Non-Elementary Reactions by Linear Regression 

The rate equation for the non-elementary reaction derived in Section 2.1.10 can be written in terms of two independent parameters k and K2 as 

In this section, we present a method for the estimation of parameters and K2 using the experimental readings on variation of Q with time recorded in a batch reactor experiment. The differential equation for variafion of Q with time is written as 

Using the Ca versus time t data recorded in the batch reactor experiment, values of Xy X2 and y are calculated and this is illustrated in Table 2.2. Using the values of Xy X2 and y listed in Table 2.2, the values of coefficienfs a- and 2 are estimated by the method of linear regression (Appendix B). Parameters ki and /C2 are calculated using the estimated values of
