## Abstract The kinetics of solvolysis of __trans__‐dichlorobis(__N__‐methylethylenediamine)cobalt(III) complex have been investigated in aqua‐organic solvent media (0–60% (v/v) cosolvent) at 25 ≤ t°C ≤ 60, using __n__‐propanol and __tert__‐butyl alcohol as cosolvents. The first‐order rate constant
Aquation rates for cis-CoCl(en)2(A)2+ (A = 3,5-lutidine, imidazole, N-methylimidazole, benzimidazole) have been determined by halide release titration in 1 .O M HNOz at 50-80°C. Kinetic parameters are (in the above order of A) 1O7k29s (sec-I), 7.4, 5.7, 1.3, 9.7; E, (kJ/mole), 103, 101, 130, 112; lo
