THERMOCHEMICAL APPROACH TO SOLID-STATE DECOMPOSITION REACTIONS AGAINST THE BACKGROUND OF TRADITIONAL THEORIES

The novel thermochemical and traditional Arrhenius approaches to solid-state decomposition reactions have been evaluated from the standpoints of the number and the validity of the assumptions introduced in the theories, and achievements obtained over the last decade in the frameworks of both approaches. As it follows from the analysis, in both respects, the thermochemical approach is preferable. The so-called 'controversial' problem of the use of thermodynamic concepts and thermochemical data for the quantitative evaluation of decomposition kinetics in the thermochemical approach has also been discussed.
