Using Fourier transform infrared spectroscopy, the ethene yield from the reaction of C2H5 radicals with O2 has been determined to be 1.50 ± 0.09%, 0.85 ± 0.11%, and 2H5 radicals with molecular chlorine was measured relative to that with molecular oxygen. (6) C2H5 + Cl2 → C2H5Cl + Cl (7) C2H5 + O2 → products A ratio k6/k7 = 1.99 ± 0.14 was measured at 700 torr total pressure which, together with the literature value of k7 = 4.4 × 10-12 cm3 molecule-1 s-1, yields k6 = (8.8 ± 0.6) × 10-12 cm3 molecule-1 s-1. Quoted errors represent 2σ. These results are discussed with respect to previous kinetic and mechanistic studies of C2H5 radicals.
