Abstract

Abstract The rate of electron exchange between vanadium (IV) and vanadium (V) in acid solutions containing chloride ion has been measured from a study of 51V nuclear resonance line broadening. It is found that the rate of electron transfer is first order in vanadium (IV) and second order in vanadium (V) and that the rate constant for the exchange reaction in 6·5 F acid solutions is k = 1·5 × 10 6 I 2/mole 2sec. In the solutions studied the lifetimes between the electron transfer events were in the range 0·81−14·7 × 10 −4 sec for vanadium (V), and in the range 1·0–6·7 × 10 −5 sec for vanadium (IV).
