Question

10. The decomposition of ozone in the upper atmosphere to dioxygen occurs by a two-step mechanism.

The first step is a fast reversible step and the second is a slow reaction between an oxygen atom and an ozone molecule:

Step 1: O3(g) O2(g) + O(g) Fast, reversible, reaction

Step 2: O3(g) + O(g) → 2O2(g) Slow

a. Which is the rate determining step?

b. Write the rate equation for the rate-determining step.

Please show full work

c. Write the rate equation for the overall reaction.
