Determination of reaction kinetics based on a part of a differential thermal analysis or thermogravimetric curve

A method is suggested for the kinetic consideration of a differential thermal analysis (DTA) or thermogravimetric (TG) curve which is based on a relation for the first-order reaction rate and Arrhenius's equation. The suggested method was tested on several different systems and during these tests it was established that, by using a part of a TG or DTA curve up to maximum reaction rate, one can obtain satisfactory results.
