Evaluation of solvation numbers and reaction orders for electrode processes of metal ions in non-aqueous media

Abstract

The coordination model of ion solvation in mixed solvents was applied to evaluate solvation numbers of cations and reaction orders with respect to the organic solvent for electrode reactions in non-aqueous media. These values were calculated from linear dependences of the Gibbs energy of transfer and logarithms of electrochemical rate constants plotted against the logarithm of organic solvent activity. This method gives credible results, but only for highly basic solvents.
