摘要

The second-order rate constant (k_2) for the aqueous-phase reaction Cl_2(aq) + OH~- → HOCl + Cl~- was determined by measuring the uptake of gas-phase chlorine into water in a bubble train flow reactor. In making these measurements, we avoided some of the difficulties encountered in earlier studies. Data were obtained at 275, 293, and 303 K, yielding k_2 = (1.3 ± 0.5) * 10~8 M~(-1) s~(-1), (6 ± 2) * 10~8 M~(-1) s~(-1), and (8 ± 3) * 10~8 M~(-1) s~(-1), respectively. The atmospheric relevance of the chlorine hydrolysis reaction is discussed.
