Popis:	The kinetics of thermal decomposition of 13 selenites has been studied under isothermal heating conditions with a derivatographer. Values of the activation energy and frequency factor in the Arrenius equation are found. It is found that between these parameters and the radius of selenite cations a close relationship exists: the greater the cation radius, the higher the thermal stability of selenites. The obtained results of the change in these parameters are interpreted by the theory of polarization interactions between ions and by the general Klopman and Hudson’s perturbation theory for ionic orbitals.
