Redox reactions of cobalt(III) complexes in aqueous organic mixtures effects: of single ion assumptions on initial state-transition state solvation analysis

Summary Solvent effects on the kinetics of redox reactions of cobalt(III) complexes were assessed in aqueous mixtures containing methanol,t-butanol, and acetone according to three different extra-thermodynamic assumptions —Wells, TATB, and TPTB^** — at 298.2 K. The calculated values of transfer functions of individual ions and initial and transition states were often markedly different. In some cases these differences led to different conclusions in the evaluation of the role of solvation in the reactions investigated.
