Abstract
The rate of hydrolysis of trans -[Cr(NH ) F ] was obtained as a function of acid
concentsation in perchloric, sulfuric and nitric acid at 3Q°C. The results have been
analyzed by the treatment of Bunnett and Olsen. Values of the parameter ?in Olsen
equation are consistent with the participation of water as a proton-wansfer agent in the rate-determining step. The Arrhenius plot for perchloric acid was linear, with an
activation energy of 19.8 ± 0.8 KCal K mole .
