Kinetics of the Reaction of Chlorine Atoms with Hydrogen Bromide

摘要

The kinetics of the reaction Cl+HBr yield HCl+Br have been studied over the temperature range 267-333 K by using the very low pressure reactor (VLPR) technique. The measured rate constant is 3.4 x 10 to the -12 power cc/molecule/s. The reaction rate was found to be independent of temperature. The A factor for the reaction is estimated on the basis of a tight transition state and agrees well with the measured rate constant.
