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 nonlinear 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 diffusionconvective energy transfer, the potential of the chemical energy transfer of a reacting system is introduced. (Author)
