摘要
The thermal stability and kinetics of decomposition of V2Se2O9 were studied under non-isothermal heating on a derivatograph. Several mathematical models were used to describe the process as well as 10 different calculation methods. The best linear dependence between the experimental data was obtained by the method of Coats-Redfern using a mechanism non-invoking equation with n = 1.15. On this basis, the values of process activation energy, pre-exponential factor in the Arrhenius equation, change of entropy, enthalpy and the Gibbs free energy were calculated for the formation of active complex by the reagent.
