Query: Marcus Electron Transfer Reactions with Bulk Metallic Catalysis   Electron transfer organic reaction rates are considered employing the classic
physical picture of Marcus wherein the heats of reaction are deposited as the
energy of low frequency mechanical oscillations of reconfigured molecular
positions. If such electron transfer chemical reaction events occur in the
neighborhood of metallic plates, then electrodynamic interface fields must also
be considered in addition to mechanical oscillations. Such electrodynamic
interfacial electric fields in principle strongly effect the chemical reaction
rates. The thermodynamic states of the metal are unchanged by the reaction
which implies that metallic plates are purely catalytic chemical agents.
