【 摘 要 】

The trans-dichlorobis(ethylenediamine)cobalt(III)chloride was synthesized in an undergraduate laboratory and its aquation reactionwas carried out at different temperatures. This reaction follows pseudo-first-orderkinetics and the rate constants, determined at 25, 35, 45, 55 and 70 ºC, are 1.44 x 10-3; 5.14 x 10-3; 1.48 x 10-2;4.21 x 10-2 and 2.21 x 10-1 s-1, respectively.The activation energy is 93.99 ± 2.88 kJ mol-1.
