Question
Ozone in the earth's atmosphere decomposes according to the equation:
2 O3(g) → 3 O2(g)
This reaction is thought to occur via the two-step mechanism:
Step 1 O3(g) ⇌ O2(g) + O(g) Fast, reversible
Step 2 O3(g) + O(g) → 2 O2(g) Slow
What rate law is consistent with this mechanism?
A.
–∆[O3]/∆t = k[O3]
B.
–∆[O3]/∆t = k[O3]2
C.✓ Correct
–∆[O3]/∆t = k[O3]2/[O2]
D.
–∆[O3]/∆t = k[O3]2/[O2]3
