According to the general differential kinetic equation of several types of reversible reactions and the thermokinetic transformation equation, the characteristics parameter method for reversible reactions, with which the rate constants of forward and backward reactions and equilibrium constant can be obtained simultaneously from a single thermogram, has been proposed in this paper. The thermokinetics of the reactions of nitroethane with ammonia at 15℃ and 25℃ and with trihydroxymethyl aminomethane at 15℃ and 30℃ have been studied with this method respectively. The validity of this method has been proved by the experimental results.
