Applicability of the Kissinger equation in thermal analysis
Web11 okt. 2014 · The famous Kissinger’s kinetic evaluation method (Anal. Chem. 1957) is examined with respect to: a) the relation between the DTA signal θ (t) and the reaction rate r(t) ≡ dα/dt; b) the requirements on reaction mechanism model f(α); and c) the relation of starting kinetic equation to the equilibrium behavior of sample under study. Distorting … WebRecently the term, “model-free kinetics” has increasingly been used in thermoanalytical studies. It is noteworthy that even without knowledge of the concrete reaction … WebIt was shown that Kissinger's equation holds for any kinetic model [52]. However, derivation of Eq. (7) require the use of an approximation for the temperature integral and the constancy of the extent of conversion at the peak maximum. This later approximation is not always fulfilled for complex reactions [53]. client centred approach to health promotion
