Abstract
The rate constant for the reaction of Br + O3 → BrO + O2 has been measured at four temperatures from 234 to 360 K by the technique of discharge flow coupled with resonance‐fluorescence detection of bromine atoms. The measured rate constants obey the Arrhenius expression k = (9.45 ± 2.48) × 10−12 exp(‐659 ± 64/T) cm3/molec·sec (one standard deviation). The results are compared with two previous studies, one of which utilized the flash‐photolysis–resonance‐fluorescence technique and the other utilized the discharge‐flow–mass‐spectrometric technique. The result is also discussed from a theoretical point of view.Keywords
