Reduced Extent Method in Studies of Thermokinetics (Ⅲ)——Studies on Thermokinetics of the 2-Ⅰ Reversible Reaction

Abstract

Abstract: On the basis of previous articles, the reduced extent equation and the model of thermokinet-ics for 2-1 reversible reaction, with which both rate constants and equilibrium constant can be calculated simultaneously, are suggested in this paper.The thermokinetics for an endothermic 2-1 reversible reaction system, the acid-catalyzed esterification between acetic acid and methanol in buffer solution (pH=1.5), has been studied with a conduction calorimeter at 30.0 and 40.0℃.The rate constants of forward and backward reactions and equilibrium constants were calculated with the model in this paper, and then, activation parameters of this reversible reaction were obtained.These experimental results, by which the validation of this model has been tested, are discussed in detail.
