Abstract

Abstract: In this paper in the light of a theoretical thermogram curve equation of the first order reaction,a novel data processing method is proposed,in which the rate constant is calculated from both selected peak-height without using any peak-area and other data.Therefore the problems arisen from the peak-area-computation or from the error in reading can be avoided.In order to test the validity of this novel method,the kinetics of the reaction between tri-ethylamine and ethyl iodide are investigated in DMSO,The rate constant calculated with this novel method is in agreement with those in the literature,and therefore the basic pnciples of this selected peak-height method are believed to be correct.
