Abstract : A quantitative semianalytic solution for the constant heating rate Arrhenius integral forms the basis of a new isoconversion method for determining both the activation energy and frequency factor of an arbitrary, single-step reaction from temperature scanning experiments independent of the form of the rate law. Advantages of the new integral method compared to existing techniques include simplicity, better accuracy, and broad applicability.
