The aquation kinetics of [Co(NH 3 ) 5 Cl] 2Ο© in dicarboxylate media containing 10% (v/v) acetone is measured in the temperature range of 35 -60Β°C. A new empirical correlation between the rate coefficient, k obs , and the stoichiometric concentration of the dicarboxylate ligand (C L ) has been establ
The equilibrium quotients for the formation of Co(NH3) SCl2+ from Co(NH3) 50Hz3+ and CI1were 3.74 f 0.25 M-' and 6.07 f 0.54 M-' at 45.OoC in 10: 1 mole ratio water: dimethyl sulfoxide and in 25 w/w yo aqueous ethanol, respectively, and those for the formation ofthe ion pair C O ( N H ~) ~O H ~~+ .
The kinetics of aquation of cis-[Co(en)z(H20)Br ] 2 + and cis-[Cr(en)2(H20)Br] 2+ (en = ethylenediamine) were investigated in aqueous mixtures of MeOH, EtOH, i-PrOH and t-BuOH. The values of transfer functions corresponding to the transfer of reactants and activated complex from water to the solvent
