Abstract

The reaction Cl + HBr→HCl + Br was studied by a competitive method using the reaction Cl + C₂H₆→HCl + C ₂H₅ as a reference reaction. Experiments to determine ratios of rate constants k_Cl+HBr/k_Cl+C2H6 in the temperature range 222-504 K were carried out in a fast flow system with mass spectrometric analysis of the reaction mixture. The results fit the Arrhenius expression: k_Cl+HBr/k_Cl+C2H6 = (0.53±0.03) exp [-(321±16)/T]. A comparison is made with values calculated from reported results for the individual rate constants K_Cl+HBr and K _Cl+C2H6.
