The rate of the bromine-exchange reaction between gallium bromide and isopropyl bromide in nitrobenzene was measured at 19°, 25°and 40℃., using isopropyl bromide labelled with Br-82. The results indicated that the exchange reaction was second order with respect to gallium bromide and first order with respect to isopropyl bromide. The third-order rate constant determined at 19℃. was 3.2 × 10-2l2mole-2sec-1. The activation energy, the enthalpy of activation and the entropy of activation for the exchange reaction were also determined.
