Abstract: | The system of coupled nonlinear diffusion equations are solved analytically for the transport and kinetics of electrons and
reactant in the layer of a modified electrode. Analytical expressions of concentrations of mediator and substrate are presented
using Homotopy perturbation method. A simple expression of electrochemical rate constant K
ME+ is also obtained for all values of reaction parameters. The available limiting case results are compared with our results
and are found to be in good agreement. |
