Consider the mechanism proposed for the decomposition of ozone in the stratosphere: Step 1:                           &n

Consider the mechanism proposed for the decomposition of ozone in the stratosphere:

Step 1:                                     O3 (g) → O2 (g) + O (g)

Step 2:                                     O3 (g) + O (g) → 2 O2 (g)

Overall reaction:                      2 O3 (g) → 3 O2 (g)

What is molecularity of the first step?

Unimolecular

Bimolecular

Termolecular
