Fig. 1. (A) Measured kinetic decay traces of the eaq− at 720 nm for electron pulse irradiated solutions at room temperature for: 0.230 (
), 0.461 (
), 0.691 (
), and 0.921 (
) mM HA. (B) Second-order rate coefficient determination from the pseudo-first-order values obtained for each HA concentration for the reaction of HA with the eaq−. The weighted linear fit corresponds to a second-order reaction rate coefficient of k (HA + eaq−) = (2.55 ± 0.10) × 109 M−1 s−1, R2 = 0.996.
