Abstract
A flash photolysis system has been used to study the rate of reaction (1), OH + CH4→ CH3+ H2O, using time‐resolved resonance absorption to monitor OH. The temperature was varied between 300 and 900°K. It is found that the Arrhenius plot ofk1is strongly curved andk1(T) can best be represented by the expressionThe apparent Arrhenius activation energy changes from 15±1 kJ/mole at 300°K to 32±2 kJ/mole at 1000°K. On either side of our temperature range, both absolute rates and their temperature dependence are in good agreement with the results from most previous investigations.Keywords
