A REVIEW OF THE MUTUAL DEPENDENCE OF ARRHENIUS PARAMETERS EVALUATED BY THE THERMOANALYTICAL STUDY OF SOLID-STATE REACTIONS - THE KINETIC COMPENSATION EFFECT

The kinetic compensation effect (KCE) has been observed in numerous kinetic studies of solid-state reactions using thermoanalytical methods. An attempt has been made to separate phenomenologically the KCE into the variation and the mutual dependence of the resultant Arrhenius parameters. The probability of the mutual dependence of the Arrhenius parameters caused by the properties of the general kinetic equation was discussed in relation to: (1) the reaction temperature interval, (2) the fractional reaction alpha, (3) the kinetic model function f(alpha), and (4) the isokinetic hypothesis. The mutual dependence of the Arrhenius parameters due to the properties of the general kinetic equation was first checked before discussing the KCE in relation to a physico-chemical factor for a series of reactions under investigation. The necessity of establishing a check system for the kinetic calculation is discussed briefly on the basis of the prerequisities of the methods of kinetic calculation and the properties of the general kinetic equation.
