A mechanism for a naturally occurring reaction that destroys ozone is:
Step 1: O₃(g) + HO(g) → HO₂(g) + O₂(g)
Step 2: HO₂(g) + O(g) → HO(g) + O₂(g)
Which species is a catalyst and what type of catalysis is occurring?

Question

Quizplus · Accepted Answer

The species HO is a catalyst because it is consumed in step 1 and regenerated in step 2. The reaction occurs in the gas phase, indicating homogeneous catalysis.
