Chemical Kinetics Isomerization of Bicyclo Hexane

Data on the thermal isomerization of bicyclo [2,1,1] hexane were measured by Srinivasan and Levi (1963). The data are given in Table 4.4. The following nonlinear model was proposed to describe the fraction of original material remaining (y) as a function of time (x,) and temperature (x2). The model was reproduced from Draper and Smith (1998) 

The elements of the (/x2)-dimensional sensitivity coefficient matrix G are obtained by evaluating the partial derivatives  

Equations 4.24 and 4.25 are used to evaluate the model response and the sensitivity coefficients that are required for setting up matrix A and vector b at each iteration of the Gauss-Newton method.
