In the previous articles~[1,2], a data processing method for studies on thermokinetics of a first order reaction in liquid phase had been developed. It was called the dimensionless parameter method, in which the dimensionless parameter and the rate constant of a reaction system were calculated from the thermogram's peak-area. In this paper in the light of a theoretical thermogram's equation of a first order reaction, a novel data processing method is proposed, in which the dimensionless parameter and the rate constant are calculated from the thermogram's peak-heights with-out using any peak-area. Thereby the problems arisen from the peak-area-computation can be avoided.
In order to test the validity of this novel method, ...
