This report consists of a critical review of the literature pertinent to the mechanism and kinetics of dissolution of gaseous nitrogen oxides into aqueous solution. Kinetic expressions applicable to mixed-phase reactions generally are presented as are specific expressions pertinent to aqueous-phase reactions of the nitrogen oxides. Kinetic studies reviewed include indirect studies, direct measurements of aqueous-phase reaction rates, and measurements of mixed-phase kinetics. The results of these various studies are compared to obtain recommended values for the pertinent equilibrium and kinetic constants at 25/sup 0/C, as follows: For the Henry's law coefficient of NO/sub 2/, (1.0 +- 0.3) x 10/sup -2/ M atm/sup -1/; for the rate constant of the aqueous phase reaction 2NO/sub 2//sub (a)/ (+H/sub 2/O/sub (l)/) - > 2 H/sup +/ + NO/sub 2//sup -/ + NO/sub 3//sup -/, (0.7 +- 0.35) x 10/sup 8/ M/sup -1/ sec/sup -1/; for the rate constant of the reaction NO/sub (a)/ + NO/sub 2//sub (a)/ (+H/sub 2/O/sub (l)/) - > 2H/sup +/ + 2NO/sub 2//sup -/, (0.3/sub /sup -/0.2//sup +0.7/) x 10/sup 8/ M/sup -1/ sec/sup -1/. Other studies pertinent to aqueous phase reactionsof NO/sub 2/ and NO with water or aqueous solution are also reviewed.
