Abstract

The oxidation of the edta ligand in the NiIIIedta- complex in the presence of dioxygen obeys a second order dependence on [NiIII(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 NiIII(edta)- complexes are involved.
