A Possible Mechanism for the Decomposition of Ozone to Oxygen

question 21

Multiple Choice

A possible mechanism for the decomposition of ozone to oxygen in the atmosphere is $\begin{array}{l}\mathrm{O}_{3}(\mathrm{~g}) \rightleftharpoons \mathrm{O}_{2}(\mathrm{~g}) +\mathrm{O}& \text { (fast equilibrium) } \\\mathrm{O}+\mathrm{O}_{3}(\mathrm{~g}) \rightarrow 2 \mathrm{O}_{2}(\mathrm{~g}) & \text { (slow) }\end{array}$

What is a rate law that is consistent with this mechanism?

• A) rate = k[O₃]
• B) rate = k[O₃]²
• C) rate = k[O₃] × [O]
• D) rate = k[O₃]² × [O₂]
• E) rate = k[O₃]² × [O₂]?¹
