Rate constants for the one-electron oxidation of ClO2(1-) and NO2(1-) by several organic and inorganic free radicals have been measured along with rate constants for several reactions of ClO2, NO2 and BrO2.The kinetics of the reactions of ClO2 and NO2 are consistent with simple electron-transfer theory, except for the reaction of NO2 with SO3(2-), which appears to be oxygen atom transfer.Equilibrium constants have been determined for the reactions of ClO2 with aniline at pH 6.9 and N,N-dimethylaniline at pH 9.6.This leads to one-electron redox potentials of 1.03 and 0.87 V for these aromatic amines, respectively, at the corresponding pH.
