Abstract |
Rate constants have been determined for the reactions of NO2 with SO3(2-) and HSO3(1-) in aqueous solutions. The rate constant increases from about 1.2 x 10 to the 7th power /M-sec near pH 5 to 2.9 x 10 to the 7th power /M-sec at pH 13. The reaction appears to involve the formation of an intermediate complex which may undergo subsequent reaction with NO2 to yield the ultimate products or may react with other substrates present. The formation of a long-lived intermediate would have implications on the chemicals of flue-gas scrubbers and on luminol-based NO2 detectors. |
