A set of parameters (species charge, kinetic constants, reaction orders and molar absorptivities) was chosen for each reaction taking account their physical meaning. The interfacial absorbance at a given wavelength in a total internal reflection mode and the voltammetric responses were simulated in order to extract kinetic and thermodynamics parameters.
