Abstract
The kinetics of the first step of base hydrolysis oftrans-bis(Hmalonato)bis(ethylenediamine)cobalt(III) [malH-=HO2CCH2CO2-] has been investigated in the 15-35° C range, I=0.3 mol dm-3 (NaClO4) and [OH-]=0.015-0.29 mol dm-3. The rate law is given by -d In[complex]T/dt=k1[OH-] and at 30° C, k1=8.5×10-3 dm3 mol-1s-1, ΔH≠=117.0±7.0 kJ mol−1 and S=99.0±24.0 JK-1mol-1. The activation parameters data are consistent with the SN1cb mechanism.
