Summary

The stoichiometry and kinetics of the oxidation of ethyl-enediaminetetraacetate by [Fe(phen)3]3+, [Fe(bipy)3]3+ and [CoIIIW12O40]5− were studied in aqueous HClO4. Reaction rates were first order with respect to the oxidants and the reductant, and the dependence of the second order rate constant k 2 on [H+] is given by k 2 = a + b[H+ −. The primary products were CO2, CH2O and (CH2NH2)2. Schuster treatment is employed to show that the reactions occur by the outersphere mechanism.
