A quantity whose expression includes a current, whose value is characteristic of a charge-transfer process and the experimental conditions under which it is investigated, and whose nature depends on the technique that is employed. Some typical response constants are the
diffusion current constant in polarography
in linear-sweep voltammetry, and the chronopotentiometric constant in chronopotentiometry.
