Abstract
A general method of regression analysis of the experimental data concerning relaxation experiments on binary compounds for the evaluation of the chemical diffusion coefficient is presented for cases in which the surface reaction exerts a partial control of the overall equilibration kinetics, assuming that the surface reaction follows a linear type of rate law. A rigorous method of analysis of data for the case of exclusive rate control by solid-state diffusion is also developed as a special solution. Application of the method to theoretically calculated curves indicates the correctness of the procedure developed. Limitations connected with the possible occurrence of forms different from the linear for the surface rate law are finally considered.
