Abstract

Electrochemical processes where the initial electrochemically active entities arise from chemical reactions between two molecules of a dormant reactant pertain to the second-order surface CE mechanism concerning the concentration of the starting agent. When the chemical reaction is reversible and the electron transfer step is quasi-reversible, the outcomes in square-wave voltammetry depend on the chemical rate parameter, the equilibrium constant for the chemical reaction, the electron transfer rate, and the starting concentration of electrochemically inert species in the voltammetric cell (cOx). In this MATHCAD simulation file, we introduce a simulation procedure for this intricate model in the context of square-wave voltammetry for the very first time. We provide readers with insights on identifying this mechanism in actual experiments and on determining both kinetic and thermodynamic parameters pertinent to the chemical and electron transfer steps. This work can assist experimenters focused on protein-film voltammetry.
