Further Studies on the Dissociation of HBr Behind Shock Waves
Abstract
Previously reported shock tube studies of the dissociation of HBr in the temperature range of 2100-4200K have been extended to lower temperatures (1450-2300K) in pure HBr. The results imply that, in the lower range of temperatures, the activation energy of dissociation can be approximated by the HBr bond energy (88 kcal/mole). It was also found that, in this temperature range, the rate of HBr dissociation is sensitive to the Br 2 dissociation rate and the HBr + Br exchange rate. It was found that the higher temperature data could also be fitted reasonably well with an HBr dissociation activation energy of 88 kcal/mole, contrary to the conclusions of previous work. A detailed review is given of the rate coefficients for the other pertinent reactions in the H2- Br2 system; namely, Br2 dissociation and reactions of HBr with H and Br.
