Abstract

The rate coefficient for the reaction NO + NO₃ → 2NO₂ (1) has been measured in a discharge flow system between 223 and 400 K. Measurements were made by laser-induced fluorescence detection of NO₃ in the presence of excess NO or by chemiluminescent detection of NO in the presence of excess NO₃. Analysis of the kinetics was made using a modified form of the usual flow equations, which explicitly accounts for the viscous pressure drop. The rate coefficients are in excellent agreement with the determination of Sander and Kircher (Chem. Phys. Lett. 1986, 126, 149). The recommended rate coefficient from this study and that of Sander and Kircher can be adequately described by the expression k₁ = (1.65 ± 0.35) × 10^-11e^{[(110±50)/T]} cm³ molecule^-1 s^-1. The possible effects of secondary chemistry on the rate coefficients determined are discussed.
