The high-temperature reaction of NO with H 2 has been studied behind reflected shock waves in the temperature range of 1760-2160 K at total pressures of 1.4 to 2.0 bar by monitoring the time-dependent H-atom concentrations in the postshock reaction zone using atomic resonance absorption spectroscopy

β¦ Synopsis
The previously available overall rate data for the H2-NO reaction have l~.en re-examined in the light of new data on elementary reaction steps, with numerical integration of the governing differential equations. The reaction HNO + NO = N20 + OH has been found to be an importanL slow step. The calculated overall initial rate is approximately second order in NO and one-half order in H2, in agreement with most of the data. The overall rate is more or less proportional to the rate of the HNO + NO reaction, which has a rate constant of 10123 Β±0-3 exp (-26000 +_ 5 000) cm3/mole sec [800=-106OC).

Flash photolysis of CH3CHO and H2CO in the presence of NO has been investigated by the intracavity laser spectroscopy technique. The decay of HNO formed by the reaction HCO + NO \* HNO + CO was studied a t NO pressures of 6.&380 torr. At low NO pressure HNO was found to decay by the reaction HNO + H
The kinetics and mechanism of the thermal reduction of NO by H2 have been investigated by FTIR spectrometry in the temperature range of 900 to 1225 K a t a constant pressure of 700 torr using mixtures of varying NO/H2 ratios. In about half of our experimental runs, CO was introduced to capture the O
## Abstract The effects of NO on the decomposition of CH~3~ONO have been investigated in the temperature range 450β520 K at a constant pressure of 710 torr using He as buffer gas. The measured timeβdependent concentration profiles of CH~3~ONO, NO, N~2~O, and CH~2~O can be quantitatively accounted f
