Room Temperature Rate Constant For H + F2

Abstract

The rate constants for H atom reactions with Cl2 and F2 have been measured by monitoring the loss rate of hydrogen atoms in the presence of excess Cl2 and F2 via time-resolved, laser-induced Lyman-alpha fluorescence. The rate constants for H + F2 and H + Cl2 were found to be 2.4 +/- 0.4 (2 sigma) x 10(exp -12) and 2.52 +/- 0.18 (2 sigma) x 10(exp -11) cu cm/molecules/s, respectively. The result for H + F2 is consistent with the recommendation of Baulch et. al. (J. Phys. Chem. Ref. Data 10 (suppl. 1) (1981)) and our k(H + Cl2) value is consistent with the majority of previous measurements.
