N2 - The influence of electrolytes, of various alcohols at low concentrations, and of temperature on the rate of the electron transfer between [Co(NH3)5Br]2+ and Fe2+ has been investigated. Specific salt effects are reported. Systems of different electrolyte composition have significantly different energies of activation. Reaction mixtures containing HClO4 as the supporting electrolyte have positive ΔC#p. The rate constant as a function of alcohol concentration passes through a minimum at low temperatures. An isokinetic relationship is found to hold with dΔH#/dΔS# = 298°K. The observed effects are tentatively ascribed to the influence of water structure.
