The kinetics of the thermal bromination of CF₃I. Determination of the bond dissociation energy D(CF₃−I)

The kinetics of the thermal bromination reaction have been studied in the range of 173–321°C. For the step equation image we obtain where θ=2.303 RT cal/mole. From the activation energy for reaction (11), we calculate that This is compared with previously published values of D (CF 3 −I). The relevance of the result to published work on k c for a combination of CF 3 radicals is discussed.
