The oxidation of HSO3? by O2 in aqueous solution is a reaction of importance to the processes of acid rain formation and flue gas desulfurization. R.E. Connick, Y.-X. Zhang, S. Lee, R. Adamic, and P. Chieng (Inorg. Chem. 34, 4543 (1995)) report that the reaction 2 HSO3? + O2 ? 2 SO42? + 2 H+ follows the rate law v = k[HSO3?]2[H+]2. Given a pH of 5.6 and an oxygen molar concentration of 2.4 × 10?4 mol dm?3 (both presumed constant), an initial HSO3? molar concentration of 5 × 10?5 mol dm?3, and a rate constant of 3.6 × 106 dm9 mol?3 s?1, what is the initial rate of reaction? How long would it take for HSO3? to reach half its initial concentration?
