Is the original Kissinger equation obsolete today: not obsolete the entire non-isothermal kinetics?

Popis výsledku v původním jazyce

Physical meaning of activation energy is analyzed from the viewpoint of non-isothermal kinetic evaluation. The term of heat inertia, meaning the degree of slowness with which the temperature of a body approaches that of its surroundings, is examined, andits impact on activation energy determination is discussed, which is particularly functional for a DTA peak kinetic appraisal. Impact of a process equilibrium background on kinetics is recollected as specifically important for Kissinger kinetic evaluation distinguishing competent case of glass cold crystallization on heating but unsuitable for melt crystallization on cooling without introducing additional thermodynamic terms. Parallel to non-Arrhenian kind of kinetics, an analogous model-free description is advocated accentuating a generalized approach by logistic functions.
