- W141131353 abstract "The gas-liquid oxidation reaction of sulfur(IV) by NO/sub 2/ has been studied at neutral pH's, i.e., 6.40 and 5.80, and low reagent concentrations, i.e., (S(IV)) approx. = 1 x 10/sup -6/ M and p/sub NO/sub 2// approx. = 1 x 10/sup -7/ atm. Major products found under these reaction conditions are H/sup +/, NO/sub 2//sup -/, and SO/sub 4//sup =/, and the stoichiometry is consistent with 2NO/sub 2/ + HSO/sub 3//sup -/ + H/sub 2/O - > 3H/sup +/ + 2NO/sub 2//sup -/ + SO/sub 4//sup =/. The reaction rate was determined by following acid production via a pH-stat apparatus as a function of mixing time constant of the gas and liquid phases (tau/sub m/ = 1.6 - 5.3 s). The reaction rate was found to be significantly controlled by mass-transfer, even at the low reagent concentrations employed, and the extrapolation to the phase-mixed condition (tau/sub m/ = O) was able to yield only a lower-limit reaction rate constant. This rate constant, for reaction rate interpreted according to an overall second-order rate expression (R = k/sup (2)/ (S(IV))(NO/sub 2/)), was 2 x 10/sup 6/ M/sup -1/ s/sup -1/ at both pH 6.40 and 5.80. However, evidence is represented of amore » complex reaction mechanism apparently involving intermediates. As estimate of the contribution of NO/sub 2/-S(IV) reaction to acid production in cloud water made using the lower-limit second-order rate constant is 3 x 10/sup -5/ M hr/sup -1/ at pH 6 and p/sub SO/sub 2// = p/sub NO/sub 2// = 3 x 10/sup -9/ atm. Although the analysis is preliminary because of the use of a lower-limit value for k/sup (2)/ and the uncertainties in reaction mechanism, such a rate would constitute a significant contribution to cloud acidification.« less" @default.
