The kinetics of pentafluoroethyl radical reactions with trichloromethane and d-trichloromethane have been studied in the static system using perfluoropropionic anhydride as a photolytic source of C2F5 radicals.The Arrhenius parameters for C2F5 radical reactions with HCCl3 and DCCl3 , based on log A 3 mol-1 s-1> = 13.40 and E=0 for the recombination reaction of C3F5 radicals, are: .The magnitude of the primary kinetic isotope effect, i.e. kH/kD=6.7 +/-4.3 at 400 K is shown to be slightly larger than might be expected on the basis of standard zero-point energy model.
