Effects of electron correlations in a simple model for adiabatic electrochemical reactions: The application to particular reactions

Adiabatic free-energy surfaces (AFES) for some typical electrode processes are calculated in the framework of the surface-molecule model for adiabatic electrochemical reactions of electron transfer previously suggested by the authors. The surfaces are analyzed using the proposed diagrams of kinetic modes. It is shown that correlation effects play a substantial role in the reactions and not only considerably diminish the free energy of activation but also lead to qualitatively different shapes of AFES in some regions of modeling parameters.
