Abstract

The temperature dependence of the rate constants for the reactions F+CH₃F and F+CH₂F₂ has been determined by a competitive method using the F+D₂ reaction as a reference reaction. Ratios of rate constants k_F+CH3F/k_F+D2 and k_F+CH2F2/k_F+D2 were determined by a discharge-flow-mass spectrometric technique at four temperatures in the ranges 189-298 and 182-298 K for the two reactions, respectively. These ratios were combined with recommended values for k_F+D2 to obtain absolute values for k_F+CH3F and k_F+CH2 F₂. The present results are compared with previous published results, which are available almost exclusively only for room temperature.
