Quasireversible cyclic voltammetry of a surface confined redox system: a mathematical treatment

By removing complications caused by transport, the surface confinement of substrate and product members of a redox pair simplifies the relationships governing transient electrode reactions, often permitting a mathematical solution even when the voltammetry is kinetically controlled. Here a non-simulative study is undertaken and applied to linear-potential-scan chronoamperometry and cyclic voltammetry. Exact equations are rederived for reversible and irreversible cases; novel quasireversible results are in the form of integrals that may be evaluated numerically.
