It is shown that the chronoamperometric response at microdisk electrodes can be derived from Neumann's integral theorem of two parameters.

Abstract
It is shown that the chronoamperometric response at microdisk electrodes can be derived from Neumann's integral theorem of two parameters. The form of the transients can be predicted for a wide range of boundary conditions and this is illustrated by the relaxation behavior of irreversible reactions in addition to that of the widely investigated example of zero surface concentration of the reactant. Corrections to the transitions due to the tertiary current distribution are derived for relaxation experiments and it is shown that the methods developed can also be applied to linear sweep voltammetry.
The steady state behavior of CE and EC catalytic reactions is formally similar to the chronoamperometry of irreversible electrode reactions and it is shown that complete descriptions can be obtained for the voltammetry of such systems.
