摘要：

Rate constants of the following equilibrium reactions were determined by pulse radiolysis at high solute concentrations: SO4.- + HNO, half arrow right over half arrow left HSO4- + NO3. [k(f) = (2.7 +/- 0.5) x 10(6) M-1 s-1, k(r) = (5.6 +/- 1.0) x 10(3) M-1 s-1] and SO4.- + NO3- half arrow right over half arrow left SO42- + NO3. [k(f) = (5.0 +/- 2.0) x 10(4) M-1 s-1, k(r) = (1.0 +/-0.2) x 10(5) M-1 s-1]. By extrapolation of the latter to zero ionic strength an approximate reduction potential of NO3/NO3-, E0 = 2.45 +/- 0.05 V can be estimated.
