摘要: The influence of the spatial dispersion solvent and effect electrical field penetration into a metal on free energy reorganization activation for heterogeneous charge transfer reactions is studied. calculations are based exactly solved model sharp metal/electrolyte interface, Born sphere ion, three-mode approximation dielectric function solvent. In sharp-interface model, in case mirror reflection, relationship tensor system comprising two contacting media with plane interface obtained, along an expression potential created by point charge. This formally coincides derived earlier Vorotyntsev Kornyshev, but it contains true bulk functions media. ion solvent, image forces, which determines dependence distance from reacting to electrode, obtained. It shown that both decrease decreasing electrode. calculation results compared estimates obtained experimental data reaction Fe3+/Fe2+ hydronium discharge.
