Description
The absolute rate constants for the reactions of H atoms and OH radicals with HBr were measured by the discharge flow technique with EPR detection. The rate constants at room temperature are k1 = (6.3 +- 0.5) x 10-12 cm3 molecule-1 s-1 for H + HBr → H2 + Br and k2 = (9.2 +- 0.7) x 10-12 cm3 molecule-1 s-1 for OH + HBr → H2O + Br. There is a discrepancy between measurements carried out by EPR-discharge flow and flash photolysis-resonance fluorescence techniques. (orig.)
