Temperature dependence of the hydrogen atom abstraction reactions of Cl/+/ and HCl/+/ with H2

Rate constants are reported for the reactions of Cl(+) and HCl(+) with H2 over the temperature range 150-400 K. The Cl(+) reaction has a positive temperature dependence that follows the Arrhenius form k1 = A exp(-169/T). The reaction of HCl(+) has a negative temperature dependence that follows the form k2 = AT to the -0.6 power. The implication of these results for interstellar chemistry is commented on. Schematic potential surfaces for the reactions are suggested.
