Study of the Reactions of OH with HCl, HBr, and HI between 298 K and 460 K.



Vladimir L. Orkin, Victor Khamaganov, Igor Larin


The reactions between OH radicals and hydrogen halides (HCl, HBr, HI) have been studied between 298 K to 460 K by using a discharge flow – electron paramagnetic resonance technique. The rate constants at room temperature were found to be kHCl(298 K) = (7.9± 1.3)×10-13 cm3 molecule-1 s- 1 with a weak positive temperature dependence, kHBr(298 K – 460 K) = (1.04± 0.2)×10-11 cm3 molecule-1 s-1, and kHI(298 K) = (3.0± 0.3)×10-13 cm3 molecule-1 s-1, respectively with a weak negative temperature dependence.
