A model of chronoamperometry of a two electrons electro-deposition reaction with the adsorption of intermediate
A single step chronoamperometry of reversible reactions complicated by the intermediate adsorption and the product deposition on inert electrodes is compared theoretically with an initial state of a simple two electrons electro-deposition. If the intermediate is highly unstable, these two mechanism...

| Summary: | A single step chronoamperometry of reversible reactions complicated by the intermediate adsorption and the product deposition on inert electrodes is compared theoretically with an initial state of a simple two electrons electro-deposition. If the intermediate is highly unstable, these two mechanisms are similar, but the mechanism with successive electron transfers is needed to explain the responses appearing generally. The stability of intermediate depends on standard potentials of two steps and on the strength of adsorption. Two limiting cases are analysed and the difference between them is described.
