AP Chemistry
5.5 Collision Model
5.4 Elementary Reactions
In the upper atmosphere, ozone (\(\text{O}_3\)) is produced when an oxygen atom reacts with an oxygen molecule in the presence of an inert third body, \(\text{M}(g)\) (such as \(\text{N}_2(g)\)), through the proposed elementary step shown below.
\[ \text{O}(g) + \text{O}_2(g) + \text{M}(g) \rightarrow \text{O}_3(g) + \text{M}(g) \]
Which of the following correctly classifies the molecularity of this elementary step and compares its collision probability to that of a typical bimolecular elementary step at the same temperature and pressure?
\[ \text{O}(g) + \text{O}_2(g) + \text{M}(g) \rightarrow \text{O}_3(g) + \text{M}(g) \]
