摘要：

The kinetics of dehydration of H2SeO3, Na2SeO3 (.) 5H(2)O, CoSeO3 (.) 2H(2)O, and NiSeO3 (.) 2H(2)O under nonisothermal conditions was studied on a derivatograph. A mathematical procedure implementing the Horowitz-Metzger and Coats-Redfern methods was used. The activation energies, frequency factors, entropies, enthalpies, and Gibbs energies of formation of activated complexes from the reagents were compared.
