# Nitric oxide gas reacts with ozone gas in the atmosphere in an elementary reaction step represented below.

\(\text{NO(g)} + \text{O}_3\text{(g)} \rightarrow \text{NO}_2\text{(g)} + \text{O}_2\text{(g)}\)

Which of the following correctly identifies the molecularity and the rate law for this elementary step?

Nitric oxide gas reacts with ozone gas in the atmosphere in an elementary reaction step represented below.

\(\text{NO(g)} + \text{O}_3\text{(g)} \rightarrow \text{NO}_2\text{(g)} + \text{O}_2\text{(g)}\)

Which of the following correctly identifies the molecularity and the rate law for this elementary step?

- **A.** Unimolecular, with a rate law of \(\text{Rate} = k[\text{NO}]\)
- **B.** Bimolecular, with a rate law of \(\text{Rate} = k[\text{NO}_2][\text{O}_2]\)
- **C.** Bimolecular, with a rate law of \(\text{Rate} = k[\text{NO}][\text{O}_3]\)
- **D.** Termolecular, with a rate law of \(\text{Rate} = k[\text{NO}][\text{O}_3][\text{NO}_2]\)
