Abstract : The equation of diffusion of a chemically reacting substance in the presence of a heterogeneous reaction on an isothermal surface is solved by the integral method using a cubic profile of the concentration in the boundary layer. This solution of the diffusion equation satisfies the power approximation of the non-linear boundary condition. If the chemical reaction rate depends on the concentration of several components, then the solution of the diffusion equation is also a function of the complex pi, which takes into account the magnitude of the initial concentrations and of the diffusion coefficients of the individual components. To generalize the resultant diffusion-convective energy transfer, the potential of the chemical energy transfer of a reacting system is introduced. (Author)
