Models of the impedance of an electrochemical interface
Electrochemical methods - Impedance measurements

The case of quasi-reversible charge transfer, controlled by matter transport, will be considered first. The only reaction taking place at the interface is the redox process: $\text{Ox}+ne\underset{k_{\text{i}}}{\overset{k_{\text{d}}}{\rightleftharpoons }}\text{Red}$

where k _d and k _i are the direct and reverse reaction rates expressed in mol · s ^-1 · m ^-2 .

The concentrations c _Red and c _Ox...
