Summary

The kinetics of oxidation of the bis(ethylenediamine)mercaptoacetatocobalt (III) ion by periodate were investigated as a function of perchloric acid concentration, ionic strength and temperature. Furthermore, the effect of a nonaqueous component of the solvent on the rate constant and activation parameters ΔH≠ and ΔS≠ in the water-t-butanol and water-methanol mixtures was estimated. The solvent effect is discussed from the viewpoint of the change in solvation of initial and transition states on going from water to a mixed solvent.
