✦ Synopsis

The accuracies of the approximation of the temperature integral of the Arrhenius law proposed by Coats and Redfern(CR), Doyle(D), Gyulai and Greenhow(GG), and MacCallum and Tanner(McT) have been tested. It has been demonstrated that these methods (only with the exception of the MacCallum and Tanner procedure) generally lead to accurate enough values of the activation energy of solid state reactions.

The accuracy of these methods increases in the sequence: CC > D = GG %-McT.

## Abstract The integral methods are extensively used for the kinetic analysis of solid‐state reactions. As the Arrhenius integral function [__p__(__x__)] does not have an exact analytical solution, different approximated equations have been proposed in the literature for performing the kinetic ana

The steady-state velocity equation is derived for the general reaction scheme containing n kinds of enzyme species connected by a network of reversible reaction steps. The general equation is represented by the net rate constants as well as the true rate constants of the individual reaction steps. U
