Question
**Proposed Mechanism for the Gas Phase Reaction between Nitrogen Monoxide and Oxygen**

The mechanism is described in two steps:

**Step 1:**
\[ \text{NO} + \text{O}_2 \rightarrow \text{NO}_3 \]

**Step 2:**
\[ \text{NO}_3 + \text{NO} \rightarrow 2 \text{NO}_2 \]

**Tasks:**

**(a) Identify the molecularity of each step in the mechanism.**

- **Step 1:** [Dropdown menu options: unimolecular, bimolecular, termolecular]
- **Step 2:** [Dropdown menu options: unimolecular, bimolecular, termolecular]

**(b) Write the equation for the net reaction. Use the smallest integer coefficients possible.**

\[ \Box \] + \[ \Box \] → \[ \Box \] + \[ \Box \]

**(c) Identify any intermediates in this mechanism.**

Intermediate: Enter formula. If none, leave box blank.

\[ \Box \]

This task involves understanding the concept of reaction mechanisms and molecularity. Molecularity refers to the number of molecules involved in a reaction step. An intermediate is a species that is formed in one step and consumed in another within a reaction mechanism. Ensure to carefully assess the given reaction steps to complete these exercises.
