Abstract
The rate of the bromine-exchange reaction between gallium bromide and n-butyl bromide in 1,2,4-trichlorobenzene and in nitrobenzene was measured at 19, 25 and 40., using n-butyl 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 n-butyl bromide. The third-order rate constant determined at is in 1,2,4-trichlorobenzene and in nitrobenzene. The activation energy, the enthalpy of activation and the entropy of activation for the exchange reaction were also determined
