✦ Synopsis

The exponential relaxation of CHI, produced by the reaction 0 + CzHa --+ CH3 + HCO, to its steady-state concentration was quantitatively monitored after the reactants were mixed. The relaxation profiles yield the rate constant of the reaction 0 + CH3 -+ HzCO + H equal to (1.85 f 0.28) X cm3/molecule-sec at 300°K. Ancillary experiments yielded values for the rate constant for the reaction of 0 atoms with C Z H ~ at 30O0K, the average of which is 7.7 X cm3/molecule-sec. The experimental technique, which employs a fast-flow reactor coupled to a photoionization mass spectrometer, is described in detail and its potential discussed.

*The difference is actually less than a factor of 2 if one uses a recent direct determination of the rate constant for the 0 -Itetramethylethylene reaction to recalculate the apparent kp in [lo].

Using the value reported in [ 191, the apparent kl becomes 11.5 x lo-".
