Kinetics of the Cl-H2 system. III. The deuterium isotope effect in Cl + H2

Article abstract of DOI:10.1063/1.445932

The rate constant for the reaction Cl+D2 was measured over the temperature range 200-500 K, using the flash photolysis-resonance fluorescence technique.These data, together with previous measurements for Cl+H2, are compared with the isotope effect measured by Persky and Klein in a static bulb.Over the range 295-500 K, our data are in excellent agreement with their results.At lower temperatures, the Cl+D2 rate constant displays an anomalous non-Arrhenius curvature.A mechanism involving the reaction of Cl atoms with vibrationally excited D2 is proposed to explain this effect.
