Question

21.39$ The oxidation of HS03 by 02 in aqueous solution is a reaction of importance to the processes of acid rain formation and flue gas desulfurization. R.E. Connick et al. (Inorg. Chem. 34, XXXXXXXXXXreport that the reaction 2 HSO; XXXXXXXXXXSO4 + 2 H+ follows the rate law v = kr [HS0312 [H12. Given pH = 5.6 and an oxygen molar concentration of 2.4 x 10-4 mol dm-3 (both presumed constant), an initial HSO; molar concentration of 5 x 10-5 mol dm-3, and a rate constant of 3.6 x 106 dm9 mol-3 s-1, what is the initial rate of reaction? How long would it take for HSO; to reach half its initial concentration?
