Measurements of Rate Constants for Termolecular Reactions of O(3P) with NO, O2, CO, N2, and CO2 Using a Pulsed Vacuum‐uv Photolysis—Chemiluminescent Method

摘要: Absolute rate constants for a number of termolecular reactions O atoms were determined at 300°K. Oxygen generated by pulsed vacuum‐uv photolyses NO, O2, CO2, and N2O monitored NO2* or CO2* chemiluminescent emission. The k, in units cm6 molecule−2·second−1, the following are: O+NO+NO→NO2+NO,   k=1.5×10−31 (± 10 %) O+NO+He→NO2+He,   k=6.65×10−32 (± 10%) O+O2+O2→O3+O2,   k=6.4×10−34 (± 25 O+O2+N2→O3+N2,   k=5.4×10−34 (± O+O2+CO→O3+CO,   k=6.7×10−34 (± O+CO+CO→CO2+CO,   k=3.2×10−36 (± O+CO+N2→CO2+N2,   k=2.2×10−36 (± O+CO+He→CO2+He,   k=1.7×10−36 (± O+CO2+CO→CO3+CO,   k〈9×10−36 O+N2+N2→N2O+N2,   k〈5×10−38.
