Absolute rate constants and Arrhenius parameters for the reaction of bromine atoms with ethane

Keith D. King,   David M. Golden  and  Sidney W. Benson  

Abstract

The direct thermal bromination of C2H6 has been studied spectrophotometrically in a static system over the temperature range 221–319°C. The kinetics agree with the mechanism, Br2⇌ 2Br· [graphic ommitted]. From measurements of initial rates, log 10(k1/1. mol–1s–1)=(11.6±0.10)–(14.0±0.25)/θ, where θ= 2.303 RT in kcal mol–1. The Arrhenius A-factor is higher than that obtained by competitive experiments, but in complete agreement with both collision theory and transition-state theory predictions. It is suggested that the Arrhenius parameters for the key reference reactions, [graphic ommitted] may need re-investigation.
