Notes:
The bimolecular rate constant for the direct reaction of chlorine atoms with methane was measured at 25°C by using the very-low-pressure-pyrolysis technique. The rate constant was found to be \documentclass{article}\pagestyle{empty}\begin{document}$$ k_1^{298} = (0.93 \pm 0.05) \times 10^{ - 13} cm^3 /mole \cdot \sec $$\end{document} In addition, the ratio k1/k-1 was observed with about 25% accuracy: K1(298) = 1.3 ± 0.3. This gives a heat of formation of the methyl radical ΔH° f 298(CH3) = 35.1 ± 0.15 kcal/mol. A bond dissociation energy BDE (CH3 — H) = 105.1 ± 0.15 kcal/mol in good agreement with literature values was obtained.
