Pressure Dependence and Third Body Effects on the Rate Constants for H+O2, H+NO, and H+CO

This paper presents measurements of the third order rate constants for the reactions H+O2+M→ HO2+M, H+NO+M→ HNO+M, H+CO+M→ HCO+M. The measurements were made by concentration analysis of hydrogen atoms by means of Lyman α photometry. All experiments were performed at room temperature. Particular emphasis was placed on the effect of changing the third body and, therefore, experiments were performed with M being H2, He, Ne, Ar, and Kr for all three reactions.
