Abstract: The kinetics of the hydrolysis of Cr(ox)2, (phen)- and Cr(ox)2 (bpy)- have been studied. The rate expression is rate = kaqn [H+] [complex ] At 40°C and at an ionic strength of 2.0 mol dm - 3 the respective second order rate constants., kaqn are 1.7 x 10-5 and 6.6 x 10-5 dm3 mol- 1 s- 1. The activation parameters are evaluated and the enthalpies of activation are compared with those of racemisation for the same complexes.
