Reaction Mechanisms, Intermediates... 48. A proposed mechanism for the photodecomposition of ozone in the atmosphere is Step 1: \( \mathrm{O}_{3}(\mathrm{~g})+\mathrm{h} v \rightarrow \mathrm{O}_{2}(\mathrm{~g})+\mathrm{O}(\mathrm{g}) \) Step 2: \( \mathrm{O}_{3}(\mathrm{~g})+\mathrm{O}(\mathrm{g}) \rightarrow 2 \mathrm{O}_{2}(\mathrm{~g}) \) Which of the following species is an intermediate? a. \( \mathrm{O}_{3} \) d. \( \mathrm{O} \) b. hv c. This mechanism has no intermediates. c. \( \mathrm{O}_{2} \) 49. A proposed mechanism for the decomposition of ozone in the atmosphere is Step 1: \( \mathrm{Cl}(\mathrm{g})+\mathrm{O}_{3}(\mathrm{~g}) \rightarrow \mathrm{ClO}(\mathrm{g})+\mathrm{O}_{2}(\mathrm{~g}) \) Step 2: \( \mathrm{ClO}(\mathrm{g})+\mathrm{O}_{3}(\mathrm{~g}) \rightarrow \mathrm{Cl}(\mathrm{g})+2 \mathrm{O}_{2}(\mathrm{~g}) \) Which of the following species is an intermediate? a. \( \mathrm{Cl} \) d. \( \mathrm{O}_{2} \) b. \( \mathrm{O}_{3} \) e. This mechanism has no intermediates. c. \( \mathrm{ClO} \) 50. The reaction \( \mathrm{NO}_{2}(\mathrm{~g})+\mathrm{CO}(\mathrm{g}) \rightarrow \mathrm{NO}(\mathrm{g})+\mathrm{CO}_{2}(\mathrm{~g}) \) is thought to occur by the following mechanism: Step 1: \( \mathrm{NO}_{2}(\mathrm{~g})+\mathrm{NO}_{2}(\mathrm{~g}) \rightarrow \mathrm{NO}_{3}(g)+\mathrm{NO}(g) \) Step 2: \( \mathrm{NO}_{3}(g)+\mathrm{CO}(g) \rightarrow \mathrm{NO}_{2}(g)+\mathrm{CO}_{2}(g) \) Which of the following species is an intermediate? a. \( \mathrm{NO}_{2} \) d. \( \mathrm{CO}_{2} \) b. NO e. This mechanism has no intermediates. c. \( \mathrm{NO}_{3} \)
