The reaction of O(3P) atoms with ethane: An HTP kinetics study from 300 to 1270 K

Rate coefficients for the O+C2H6 reaction have been measured using the high-temperature photochemistry (HTP) technique. Strong non-Arrhenius behavior is observed. The data are well fitted by the empirical expression k(T)=1.9×10−31 T6.5 exp(−138 K/T) cm3 molecule−1 s−1. Confidence limits are discussed in the text. The results are consistent with calculations based on transition state theory and tunneling through an Eckart barrier.
