Abstract
This paper outlines the different ways of taking the distance from thermody namic equilibrium into account in kinetic studies based on thermoanalytical experiments. The three main approaches are: (i) avoiding or neglecting the effect of the reverse reaction, (ii) describing the influence of distance from equilibrium on apparent kinetic parameters, and (iii) incorporating a driving force factor in the rate equation. Finally, the contradiction of th e microscopic nature of the processes and the macroscopic character of the usual rate equation are briefly discussed.
