摘要
In this paper, a relationship between the value of a at the maximum reaction rate (alpha(max)) and the reaction mechanism has been deduced mathematically from the fundamental rate equations for the solid state reaction. This relation can be expressed as f'(alpha(max)) G(alpha(max)) = - 1 + 2RT(max)/E The effect of activation energy on alpha(max) has also been discussed. When E/RT(max) > 20, the values of alpha(max) fall in a narrow range dependent on the reaction mechanism. This work gives a theoretical verification to the kinetic analysis procedure proposed by Dollimore and co-workers.
