Notes:
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 of k1 is strongly curved and k1 (T) can best be represented by the expression \documentclass{article}\pagestyle{empty}\begin{document}$$k = 10^{3.54 \pm 0.08} T^{3.08} \exp (- 1010/T){\rm cm}^{\rm 3} /{\rm mole} \cdot {\rm sec}{\rm .}$$\end{document}The 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.
