**Nitric Oxide Reaction Study**

**9. Study of the Reaction:**
Nitric oxide (NO) reacts with hydrogen (H₂) to form nitrous oxide (N₂O) and water (H₂O), following the chemical equation:
\[ \text{2NO}_{(g)} + \text{H}_2{_{(g)}} \rightarrow \text{N}_2\text{O}_{(g)} + \text{H}_2\text{O}_{(g)} \]

**Experimental Data:**
In a series of experiments, the initial rates of disappearance of NO were recorded as shown below. 

\[
\begin{array}{|c|c|c|c|}
\hline
\text{} & \text{Initial Concentrations} & \text{} & \text{Initial Rate of Reaction} \\
\hline
\text{} & \left[\text{NO}\right] & \left[\text{H}_2\right] & \text{} \\
\hline
\text{Exp. 1} & \text{3.2 X 10}^{-3} \text{M} & \text{1.1 X 10}^{-3} \text{M} & \text{1.3 X 10}^{-5} \text{M/s} \\
\hline
\text{Exp. 2} & \text{6.4 X 10}^{-3} \text{M} & \text{1.1 X 10}^{-3} \text{M} & \text{5.2 X 10}^{-5} \text{M/s} \\
\hline
\text{Exp. 3} & \text{3.2 X 10}^{-3} \text{M} & \text{2.2 X 10}^{-3} \text{M} & \text{2.6 X 10}^{-5} \text{M/s} \\
\hline
\end{array}
\]

**Tasks:**

**a. Determination of the Rate Law Expression:**
To find the rate law expression for this reaction, analyze the changes in the initial concentrations and their corresponding rates.

**b. Identification of the Rate Law Graph:**
Three graphs are provided that represent potential rate laws with respect
