A proposed mechanism for the photodecomposition of ozone in the atmosphere is
Step 1: O₃(g) + h $\nu$ $\rightarrow$ O₂(g) + O(g)
Step 2: O₃(g) + O(g) $\rightarrow$ 2 O₂(g)
Which of the following species is an intermediate?

\nu

\rightarrow

O₂(g) + O(g)
Step 2: O₃(g) + O(g)

\rightarrow

2 O₂(g)
Which of the following species is an intermediate?

Quizplus · Accepted Answer

The intermediate is the species that is produced in one step and consumed in another. In this mechanism, O is produced in Step 1 and consumed in Step 2.
