| Abstract: | On the basis of literature 1], the relation between the peak height at time t and the peak area before time t for the thermogram of the first order reaction is derived. The equations including the rate constant of the first order reaction, cooling constant of calorimeter, and total area uhdef the curve With dimensionless parameter as variable are also derived.The method for evaluating dimensionless parameter R with fitting of a curve is proposed. The rale constants of three reactions calculated with this method are in agreement with those in the literatures. |
