Resonance Fluorescence Measurement of the Rate Constant of the Reaction of Chlorine Atoms with CF₃Br at Temperatures of 273–353 K

The rate constant of the reaction of chlorine atoms with CF₃Br was measured at temperatures of 273–353 K by resonance fluorescence. The experimental rate constants increased when the experiments were performed at lower temperatures. Measurements at 295 K were carried out under different conditions of chlorine atom diffusion to the reactor wall. The reaction of the chlorine atom with CF₃Br was assumed to occur on the reactor surface. The possibility of this reaction occurring during fire extinguishing at various industrial facilities was discussed.
