Abstract

The method of kinetic analysis of isothermal traces recently proposed by Dharwadkar et al. is criticized. It is concluded that this method would be a proper one in the case of reactions following the mechanism of Prout and Tompkins or Avrami-Erofeev, but it would lead to misinterpretation when diffusion or phase-boundarycontrolled reactions are involved.
