Abstract

The temperature dependence of the rate constant for the reaction F+C ₂H₆ has been determined by a competitive method using the F+CH₄ reaction as a reference reaction. Ratios of rate constants k_F+C2H6/k_F+CH4 were determined by a discharge-flow-mass spectrometric technique at four temperatures in the range 189-298 K. These ratios were combined with values of k_F+CH4 from an earlier study to obtain absolute values for k_F+C2H6. The Arrhenius expression calculated from the results is k_F+C2H6=(1.95±0.25)× 10^-10exp[-(180±70)/T] cm³ molecule^-1 s^-1. The present results are compared with previous published results.
