Kinetics of one-electron transfer reactions involving ClO/sub 2/ and NO/sub 2/
Rate constants for the one-electron oxidation of ClO/sub 2//sup -/ and NO/sub 2//sup -/ by several organic and inorganic free radicals have been measured along with rate constants for several reactions of ClO/sub 2/, NO/sub 2/, and BrO/sub 2/. The kinetics of the reactions of ClO/sub 2/ and NO/sub 2/ are consistent with simple electron-transfer theory, except for the reaction of NO/sub 2/ with SO/sub 3//sup 2 -/, which appears to be oxygen atom transfer. Equilibrium constants have been determined for the reactions of ClO/sub 2/ 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. 55 references, 3 figures, 2 tables.
