Kinetic studies of the outer-sphere electron transfer reaction between[Co(tmen)3]3+ and[Fe(CN)6]4- have been carried out at various temperatures and pH values. The ion-pair formation constant Qip of the precursor complex[Co(tmen )3]3+[Fe(CN)6]4-is 5.6×102L·mol-1, and the rate constant ket for the electron transfer within the ion-pair is 6.8×10-3 s-1 at 25℃ and I=0.10 mol/L. The activation enthalpy and the activation entropy of this reaction are 1.6×102 kJ/mol and 6.5×102J/mol·K respectively. The mechanism of the reaction is discussed.
