Extension of the improved “heterogeneous equivalent” method to the digital simulation of the slow psuedo-first order homogeneous reactions coupled to the electrode reaction

Abstract

The improved “Heterogeneous Equivalent” method for simulation of very fast first and pseudo-first order homogeneous reactions coupled with electrode reaction has been extended for the treatment of moderately fast and slow homogeneous reactions. New algorithms have been developed avoiding the simulation of homogeneous kinetics through finite difference approximation. Instead, the analytical expression for the term containing the kinetic parameter has been included in combination with other constant parameters (such as the diffusion coefficient).
