The volumes of activation for the aquation of Co(NH3)5Cl2+ and Cr(NH3)5NCS2+ in aqueous acidic solution (0.1 M HClO4) have been measured and found to be −7.5 ± 1 and −8.6 ± 1 ml/mole, respectively. These values are more consistent with an SN1 than an SN2 pathway for the aquation of both of these complexes.
