Abstract
The effect of the solvent on rate of the oxidation of [Co(en)2SCH2CH2NH2]2+ by S2O8 2− in aqueous mixtures of methanol (MeOH), tert-butyl alcohol (ButOH), acetonitrile (AN), ethylene glycol (EG) and ethylene carbonate (EC) has been analysed as regards initial and transition state contributions. From kinetic measurements and solubilities of the reactants, the Gibbs transfer functions, ΔG t°, corresponding to transfer of reactants and activated complex from water to water-organic mixtures were evaluated. The trends of the transfer functions are discussed in terms of ion-solvent interactions and the structural effects in the solvent mixtures.
