The kinetic study of the substitution reaction of lead(II) and ethylenediaminetetraacetatocobaltate(II) complexes in aqueous solutions has been carried out by a similar method as reported previously. The reaction was found to proceed through four simultaneous reaction paths and to be characterized by involving the dissociation of ethylenediaminetetraacetatocobaltate(II) complexes as a rate-determining process. The rate constants of the rate-determining steps of four reaction paths were determined at ionic strength 0.2 at 5 and 15°C. It was confirmed also that this substitution reaction proceeds through both hydrated and monoacetato lead(II) ions.
