Theoretical studies using the dα dt = k(T)f(α) rate equation for heterogeneous processes - especially those involving at least one solid reactant - are reported. Dependence of k on the sample size is shown in general. Possible rate expressions for reversible systems are discussed. New forms analogous to physical fluxes and current densities are presented for the kinetic description of the chemical step of the processes concerned.
