摘要：

The influence of the selection of the f(alpha) function, which represents the reaction/process mechanism, on the values of the resulting kinetic parameters is discussed. It has been found that the solutions, in the form of the Arrhenius equation constants, show an isokinetic effect over a wide range of temperature. A special relationship between alpha (degree of conversion), E and T holds for low values of degree of conversion.
