The kinetics of oxidation of [Co(en)2SCH2COO]+ with S2O82- was studied in water-methanol and water-tert-butyl alcohol mixtures. Changes in the reaction activation parameters ∆H≠ and ∆S≠ with varying concentration of the co-solvent depend on the kind of the latter, which points to a significant role of salvation effects. The solvation effect on the reaction is discussed based on a comparison of the transfer functions ∆Ht0, ∆St0 and ∆Gt0 for the initial and transition states with the changes in the activation parameters accompanying changes in the CO-solvent concentration. The transfer enthalpies of the reactant were obtained from calorimetric measurements.

We have measured the viscosity coefficient B of the electrolytes NaCl and Bu4NBr in aqueous-organic mixtures containing up to 40% by weight of tert-butyl alcohol (TBA), as well as that of the non-electrolyte TBA in aqueous solutions of the salts NaCl and Bu4NBr. The variations of B were compared with those of the thermodynamic quantities ΔHtθ and ΔStθ of the solutes studied in these different media. The contribution of the solute to the free enthalpy of activation of viscosity has also been calculated.
