of with O2, N2O, CO2, NO and SO2 in the temperature range 298–523 K is reported. The bimolecular rate constants are described in Arrhenius form by k(O)2) = (1.7 ± 0.4) × 10−10 exp(−7.9 ± 0.7 kJ/mol/RT) cm3 s−1, k(N2O) = (1.7 ± 0.3) × 10−10 exp)−12.0 ± 0.6 kJ/mol/RT) cm3 s−1, k(CO2) = (7.3 ± 1.3) × 10−11 exp(−12.3 ± 0.6 kJ/mol/RT) cm3 s−1 where the uncertainties are ±2σ. The rate constants with NO and
据报道,在298–523 K的温度范围内,O 2与N 2 O,CO 2,NO和SO 2的气相反应性。双分子速率常数以Arrhenius形式描述为k(O)2)=(1.7±0.4)×10 -10 exp(-7.9±0.7 kJ / mol / RT)cm 3 s -1,k(N 2 O) =(1.7±0.3)×10 -10 exp)-12.0±0.6 kJ / mol / RT)cm 3 s -1,k(CO 2)=(7.3±1.3)×10 -11exp(-12.3±0.6 kJ / mol / RT)cm 3 s -1,其中不确定度为± 2σ。NO和SO 2的速率常数对温度不敏感,室温速率常数分别为1.5×10 -11和2.0×10 -10 cm 3 s -1。所有反应物的消失率与总压力无关,表明双分子提取机理。
