摘要

The absolute rate constant for the reaction F(~2P) with Cl_2 has been measured using the discharge flow kinetics technique coupled to mass spectrometric detection at T = 180-360 K and 1 Torr He nominal pressure. Experiments were performed at NASA Goddard Space Flight Center (GSFC) in Greenbelt, MD, and Laboratoire de Combustion et Systemes Reactifs-CNRS in Orleans, France. Results of k = (5.7 ± 0.8) * 10~(-11) and (6.2 ± 0.8) * 10~(-11) cm~3 molecule~(-1) s~(-1) independent of temperature were obtained by each laboratory, respectively. When the results from both laboratories were combined into one data set, an average temperature independent value of k_1 = (6.0 ± 1.1) * 10~(-11) cm~3 molecule~(-1) s~(-1) was obtained. A very slight positive temperature dependence with k_1(T) = (6.5 ± 1.5) * 10~(-11) exp{-(20 ± 60)/T} cm~3 molecule~(-1) s~(-1) may also be derived from the combined data in the range T = 180-360 K.
