Abstract: | The reaction of CF3 radicals with H2O (D2O) has been studied over the range of 533–723 K using the photolysis and the pyrolysis of CF3I as the free radical source. Arrhenius parameters for the reactions where X = H or D, relative to CF3 radical recombination are given by where k/k is in cm3/2/mol1/2·s1/2 and θ = 2.303RT/cal/mol. The activation energy and the primary kinetic isotope effect have been compared with those derived from the BEBO method. |
