Abstract

The oxidation of the edta ligand in the Ni^IIIedta^- complex in the presence of dioxygen obeys a second order dependence on [Ni^III(edta)^-] and a first order dependence on [O₂], k=(2.0±0.4)×10⁸ dm⁶ mol^-2 s^-1, indicating a cooperative mechanism of oxidation in which one molecule of dioxygen and two Ni^III(edta)^- complexes are involved.
