WebA simple redox reaction is one that involves a change in the electrical charge of a charge carrier, usually a simple or complex ion in the solution, by its taking away, an electron from the electrode (reduction), or its giving an electron to the electrode (oxidation). The same carrier may be present in solution in two states of charge. WebMar 12, 2024 · The Butler-Volmer equation is therefore the more general formulation. We note that there are more sophisticated approaches based on the electron transfer theory by Marcus and Hush, which assumes that the charge transfer kinetics is dominated by a reorganization of the solutes in the adjacent layers due to a change of charge.
