Question 3. High concentrations of chlorine radicals (CIOx = CI+ CIO) in the antarctic spring stratosphere cause rapid destruction of 03. Recent observations indicate that the extent of Os depletion in antarctic spring is ultimately limited by conversion of CiOx to the long-lived HCl reservoir as O3 concentrations fall to very low levels. Consider an air parcel in the antarctic spring stratosphere containing 0.8 ppmv CH, 0.6 ppmv O3, 0.3 ppbv NOx, and 1.0 ppby CiOx, with an air density n. = 3.5x108 molecules cm3. The following reactions cycle the CiOx and NOx radicals: CI + O3 CIO + O2 CIO + NO CI + NO NO + 03 NO2 + O2 + (1) (2) (3) k= 7.9 x 10-12 cm molecules! ke=2.7 x 10-11 cm molecule 1 g1 k3= 1.8 x 10-15 cm moleculell NO, + hy NO + O2 (4) ka= 1 x 10 (a) Assuming steady state for CIOx and NOx radicals, show that [Cl]
