Plausible pathways consistent with the experimental rate law are discussed. An iodine bridged activated complex between reactant and substrate species is proposed to explain the electron mobility from arsenic to vanadium by ‘resonance transfer'. Applying other criteria, the heterolytic dissociation of the vanadium-iodine bond of the activated complex is considered rate-controlling.
