Both involve high-pressure electrochemistry. One is the measurement of the pressure dependence of the rate constant for electron transfer in a given couple at an electrode, but it is not immediately clear how feg] and the corresponding volume of activation relate to feex and AV, respectively, for the self-exchange reaction of the same couple. This is a major theme of this chapter, and is pursued in detail below. The other method involves invocation of the cross relation of Marcus [5], which expresses the rate constant ku for the oxidation of, say, A by B+ in terms of its equilibrium constant and the rate constants kn and fe22 for the respective A+/A and B+/B self-exchange reactions ...

Application of electrochemical methods can be suitable for certain oxidation-reduction reactions. Both homogeneous and heterogeneous electron transfer reactions have been investigated electrochemically. The technique and apparatus can range from reasonably standard cyclic voltammetry and rapid scan voltammetry to quite specialized arrangements.In the latter case, the method often needs to be adapted to the context of a particular reaction. An example of high-pressure electrochemistry apparatus is shown in Figure 6.

Summarising these points, only a part of high-pressure electrochemistry belongs to high-temperature electrochemistry. Supercritical electrochemistry in gases with low critical temperature like carbon dioxide or sulphur dioxide, however, is not...
