Analog Thermogram Method(Ⅲ)──Reversible Reactions

Abstract

Abstract: According to the theoretical bases of thermokinetics and analog thermogram method, a general analog thermogram method for several types of reversible reactions, with which the rate constants of forward and backward reactions and equilibrium constant can be calculted from the same thermogram simultaneously, has been proposed in this paper. The thermokinetics of the reactions of nitroethane with ammonia at 15℃ and 25℃ and with tris (hydroxymethyl)aminomethane at 15℃ and 30℃ have been studied with this method,re-spectively. The results of rate constants and equilibrium constants calculated with this method are in agreement with those in literatures. Therefore, the analog thermogram method for the reversible reactions is believed to be correct.
