Kinetics of the Reaction of Chlorine Atoms with Hydrogen Chloride.

Abstract

Atomic fluorine was reacted with HCl in a flow system to see if the F + HCl yields HF + Cl reaction could be used as a titration for determination of F atom concentration, with an endpoint indicated by the intensity of chlorine atom recombination emission. A sharp intensity maximum of this emission was observed near the endpoint, indicating the rapid removal of chlorine atoms by excess HCl. Since kinetic studies indicated that this removal process was third order overall and first order in Cl, the Cl + HCl + M yields HCl2 + M reaction was hypothesized. Third order rate constants were determined for M = HCl, Ar, and N2. The relative efficiencies were found to be Ar:N2:HCl = 1:7.9:19.5.
