Abstract
Isotopically labelled atomic oxygen, produced by the photolysis of N18O2 at 3660 Å, was allowed to react with CO, CO2, N2O, O2 and COCl2, respectively. The rates and mechanisms of the exchange reactions are discussed. The specific rate constants were determined for the process, O*+XO→O*X+O. They are 6.2 × 1010 exp [(–6900±700)/RT], 6.3 × 108 exp [(–3500±200)/RT], 9.6 × 108 exp [(–4400±800)/RT], and 3.9 × 109 exp [(–1100±400)/RT] 1. mole–1 sec–1 for CO, CO2, N2O and O2 respectively.Keywords
