The reaction of CH 2 O with NO 2 has been studied with a shock tube equipped with two stabilized ew CO lasers. The production of CO, NO, and H 2 O has been monitored with the CO lasers in the temperature range of 1140–1650 K using three different Ar‐diluted CH 2 O‐NO 2 mixtures. Kinetic modeling and sensitivity analysis of the observed CO, NO, and H 2 O production profiles over the entire range of reaction conditions employed indicate that the bimolecular metathetical reaction, NO 2 + CH 2 O → HONO + CHO (1) affects most strongly the yields of these products. Combination of the kinetically modeled values of 1 with those obtained recently from a low temperature pyrolytic study, ref. [8], leads to\documentclass{article}\pagestyle{empty}\begin{document}$$ k_1 = 8.02 \times 10^2 T^{2.77} e^{ - 6910/T} {\rm cm}^{\rm 3} /{\rm mol sec} $$\end{document}for the broad temperature range of 300–2000 K.
