The Kinetics of Substitution Reactions Involving Metal Complexes. II. Effect of Acetate Ions on the Reaction between Copper(II) and Lead-Ethylenediaminetetraacetate Complexes

Abstract

Abstract The effect of acetate ions on the rate of the substitution reaction of copper(II) and lead-EDTA complexes is explained quantitatively on the basis of the formation of acetato complexes of copper (II) and lead(II) in acetate media and on the assumption that the substitution reaction proceeds only through the hydrated metal ions. The rate constants, the heats of activation and the entropies of activation for three elementary reactions are recalculated with the experimental results obtained previously.
