A proposed mechanism for the decomposition of ozone in the stratosphere is:
Step 1: Cl(g) + O₃(g) $\rightarrow$ ClO(g) +O₂(g)
Step 2: ClO(g) +O₃(g) $\rightarrow$ Cl(g) + 2 O₂(g)
What is the molecularity of step 1?

Question

A proposed mechanism for the decomposition of ozone in the stratosphere is:
Step 1: Cl(g) + O₃(g)

\rightarrow

ClO(g) +O₂(g)
Step 2: ClO(g) +O₃(g)

\rightarrow

Cl(g) + 2 O₂(g)
What is the molecularity of step 1?

Quizplus · Accepted Answer

The molecularity of step 1 is bimolecular because it involves two molecules reacting together: Cl(g) and O3(g).
