O + C2H5 -> CH3 + CH2O

SOURCE:

Rate coefficient is from Slagle et al. (1988) for the overall rate coefficient multiplied by the 0.17 branching fraction to this channel recommended by Tsang and Hampson (1986).

COMMENTS:

The main product channel, reaction 286 producing CH3CHO and H, was not adopted in GRI-Mech 2.1 in order to avoid accounting for CH3CHO reactions in that release of the mechanism.
