%X The acid decomposition kinetics of the monocopper complexes of 20 different linear polyamines have been studied over a range of acid concentrations (0.025 to 0.5 mol dm-3), I 1.0 (NaNO3). Complexes which contain only six-membered chelate rings reacted at a rate which is independent of acid concentration. Complexes with five-membered chelate rings have rate constants which show a non-linear dependence on H+ concentration. Activation parameters have been determined for some complexes. A mechanism, in which the breaking of the first copper-nitrogen bond or the subsequent protonation of the nitrogen atom is the rate-determining step, is proposed.
