An approximate method is put forward allowing one to extract information on the parameters determining rate constants (activation energies and frequency factors) from non-isothermal measurements of quantities proportional to the concentrations of reactants. The method, based on an approximate solution of a first-order kinetic equation in a non-isothermal regime, has been extended to fractional-heating experiments - a technique often used to extract parameters of the distributions of rate constants.
