摘要
The conditions are determined under which a low frequency inductive arc is observed on the impedance diagrams of an electrode where a reaction consisting of two successive electron transfer steps proceeding by an adsorbed intermediate species is occurring. Impedance zone diagrams make it possible to predict every possible way in which impedance diagrams evolve with the electrode voltage. In particular, sequences comprising low frequency inductive diagrams are studied.
