摘要：

Shock-tube studies were made of the thermal dissociation rate of HBr in Ar over the 2100°-4200°K temperature range, using ir emission and uv absorption techniques. It was necessary to invoke a low activation energy (compared to bond energy) in order to explain the HBr dissociation data. The rate constant found for HBr dissociation by Ar was 1012·19 exp (-50000/RT) cc/mole·sec. It was also found that HBr is about 15 times more efficient than Ar as a collision partner in dissociating HBr.
