KINETICS OF THE REACTION H + CH4 = CH3 + H2

Abstract
The reaction H + CH4 = CH3 + H2 has been studied in the temperature range 99° to 163 °C. The rate constant is given by the expression k = 1.7 × 10−14 exp (−4500/RT). The data are in agreement with the results, but not the interpretations, of previous work. The entropy of the methyl radical has been calculated for several temperatures.
