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 2?

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 2?

Quizplus · Accepted Answer

The molecularity of a reaction step refers to the number of reactant molecules involved in that step. In step 2, there are two reactant molecules: ClO(g) and O3(g), making it bimolecular.
