Timeparameter Method(Ⅳ) Studies on Thermokinetics for Opposite Reaction

Abstract

Abstract: According to the theoretical basis of thermokinetics and the general kinetic equation of opposite reaction, a novel thermokinetic research method, time-parameter method for opposite reaction, was proposed in this paper. The rate constants of forward and backward reactions and equilibrium constant can be calculated from the same thermoanalytical curve simultaneously with this method. In order to test the validity of this method, the proton-transfer reactions of nitroethane with ammonia at 15℃ and 25℃, and with hydroxymethyl aminomethane(Tris) at 15℃ and 30℃ have been studied, respectively. The results of rate constants and equilibrium constants calculated by using this method are in agreement with those in literatures.
