Electron transfer reaction between cytochrome c and trisoxalatocobalt(III)†
Abstract
The irreversible outer-sphere electron transfer reaction between the oxidant [Co(ox)3]3− and the redox
[CoIII(ox)3]3− +
was studied as a function of pH, concentration, temperature and pressure using UV–Vis and stopped-flow techniques. The concentration dependence of the observed rate constant showed a saturation of the rate constant at high concentrations of [Co(ox)3]3−, indicative of effective precursor formation between the reactants. The temperature (6–35 °C) and pressure (up to 1300 atm) dependencies at low and high complex concentrations were carried out and
