Abstract: | The rates of decay of O(3P) atoms in H2/CO/N2 mixtures in a discharge flow system have been measured, using O + CO chemiluminescence. The mechanism is: O + H2 → OH + H (1), O + OH → O2 + H (2), CO + OH → CO2 + H (3). At 425 K, k2/k3 = 260 ± 20; literature values of k3 combine to yield k2 = (2.65 ± 0.52) × 1010 dm3 mol?1 s?1. |
