Rate constant of H atom reaction with Br2 determined between 220 and 950 K

Résumé

Rate constant of the reaction H + Br2 → HBr + Br (1) has been measured in a discharge flow reactor with mass spectrometric monitoring of the species involved: k1 = 7.06 × 10−11 (T/298)0.88 exp(182/T) cm3 molecule−1 s−1 at T = 220 – 950 K (with estimated total uncertainty on the rate constant of 15% at all temperatures). The kinetic data in the present work challenge previous experimental measurements and support the most recent theoretical calculations
