Question
The following mechanism has been proposed for the formation of \( \text{N}_2 \) and \( \text{H}_2\text{O} \) from \( \text{H}_2 \) and nitrogen monoxide.

**Step 1**  
\[ 2 \, \text{NO} \rightleftharpoons \text{N}_2\text{O}_2 \quad \text{(fast, equilibrium)} \]  
This is reversible.

**Step 2**  
\[ \text{N}_2\text{O}_2 + \text{H}_2 \rightleftharpoons \text{N}_2 + \text{H}_2\text{O} \quad \text{(fast, equilibrium)} \]  
This is reversible.

**Step 3**  
\[ \text{N}_2\text{O}_2 + \text{H}_2 \rightarrow \text{N}_2 + \text{H}_2\text{O} \quad \text{(slow, RDS)} \]  
This is not reversible.

a. What is the overall reaction for this mechanism? Answer this question within the test and not on the scratch paper.

b. What are the intermediates of any result? Answer this question within the test and not on the scratch paper.

c. Write a rate law for each step of the mechanism and list the molecularity of each step. Be sure to include any reversible steps as well. Answer this question on the scratch paper clearly labeled.

d. What is the predicted rate law for this reaction? Be sure to show all your work to receive credit. Answer this question on the scratch paper clearly labeled.

e. What are the expected units for k given the time in units of seconds. Answer this question within the test and not on the scratch paper.
