چکیده انگلیسی
The kinetics and mechanism of the reactions of OH radicals with IBr and HOI have been studied using the mass spectrometric discharge-flow method at 320 K and at a total pressure of 1 Torr of Helium. The rate constant of the reaction OH + IBr â products (1) was measured under pseudo-first order conditions either in excess of IBr or in excess of OH radicals: k1 = (1.4 ± 0.4) Ã 10â10 cm3 moleculeâ1 sâ1. Both HOI and HOBr were detected as products of reaction (1) and the branching ratios 0.84 ± 0.07 and 0.14 ± 0.05, respectively, were found for the channels forming these species. For the reaction OH + HOI â products (2) the total rate constant was determined from the kinetics of HOI consumption in excess of OH radicals: k2 = (5.0 ± 1.2) Ã 10â12 cm3 moleculeâ1 sâ1.
