Abstract
The integral methods are extensively used for performing the kinetic analysis of solidstate reactions As the Arrhenius integral function pu does not have an exact analytical solution many approximations have been proposed One popular type of approximations is called the exponent approximation which can be put in the form pu = ea+blnu+cu In this study a systematic analysis of the errors involved in the determination of the kinetic parameters calculated by the integral methods based on the exponent approximations for pu has been carried out The results have shown that the precision of the kinetic parameters computed from the integral methods analyzed in this paper depends on u and the errors of the kinetic parameters determined from Doyle approach are the largest
