Determination of the Most Probable Mechanism Function

The following equation was used to estimate the most correct reaction mechanism, i.e., g(a) function [42,43,46]  

Plotting ln[g(a)] versus ln(q) and using the method of least squares linear regression, if the mechanism studied conforms to certain g(a) function, the slope of the straight line should be equal to -1.0000 and the linear correlation coefficient should be equal to unity. The values of E and A do not influence the shape of the most correct reaction mechanism function determined. In order to determine of the most probable mechanism function, the values of the conversion a corresponding to multiple heating rates taken at the same temperature were put into the left side of Eq. (22.20) and all the 35 types of mechanism functions presented in Table 22.2 were tested. The slope and correlation coefficient were obtained from the plot of ln[g(a)] versus ln q).
