| Abstract: | The reaction is first order both in vanadium(V) and substrate and is markedly inhibited by H+ ions. Kinetic evidence for the formation of a 1 1 complex of vanadium(V) and EDTA is obtained. The stability constant of this complex and its thermodynamic parameters were evaluated. A suitable mechanism is proposed.
