✦ Synopsis

The reactions of C1 and Br atoms with HzOz have been studied in the range of 300-350 K using the very-low-pressure-reactor technique. It was found that metathesis to produce HX and H02 is the only significant process (199%). For the reaction of Br 2 Br + HzO2 + HBr + HOz k z (300 K) = 1.3 f 0.45 X activation energy of 4.6 f 0.7 kcal/mol. Using an estimated A factor for A2, we find and k2 (350 K) = 3.75 f 1.1 X cm3/molecules~s, with an k 2 (bent transition state) = 1.6 x 10-11-4.3/8 k z (linear transition state) = 4 x iO-12-35/@

suggesting that a best choice is Ez = 3.9 f 0.4 kcal/mol. The relation of these values to AHj'(HO2) is discussed.
