✦ Synopsis

The kinetics of the title reactions have been studied using the discharge-flow mass spectrometic method at 296 K and 1 torr of helium. The rate constant obtained for the forward reaction

(1), using three different experimental approaches (kinetics of Br Br ϩ IBr : I ϩ Br 2 consumption in excess of IBr, IBr consumption in excess of Br, and I formation), is:

The rate constant of the reverse reaction:

Rate coefficients for the reaction of OH with Cl 2 , (k 1 ), Br 2 , (k 2 ) and I 2 , (k 3 ), were measured under pseudo-first-order conditions in OH. OH was produced by pulsed laser photolysis of H 2 O 2 (or HNO 3 ) and its temporal profile was monitored by laser-induced fluorescence. The measured r
