ChemInform Abstract: Kinetics of Reduction of Tris(ethylenediamine)cobalt(III) by Ethylenediamine-NNN′N′-tetra-acetatochromate(II).

ChemInform Abstract

The title reduction is first order in both reagents, with a second-order rate constant of 3.37·10³ dm³/mol·s at 25 °C, pH 4.81, unit ionic strength. Activation parameters (ΔH^‡=56 kJ/mol, ΔS^‡=12 J/K·mol) are consistent with weak electrostatic attraction between the reactants.
