Question
The reaction

\[ 2\text{NO}(g) + \text{Cl}_2(g) \rightarrow 2\text{NOCl}(g) \]

was studied at -10°C. The following results were obtained where

\[ \text{Rate} = -\frac{\Delta[\text{Cl}_2]}{\Delta t} \]

A table of initial concentrations and rates is presented as follows:

| \([\text{NO}]_0\) (mol/L) | \([\text{Cl}_2]_0\) (mol/L) | Initial Rate (mol/L·min) |
|--------------------------|-----------------------------|-------------------------|
| 0.12                     | 0.12                        | 0.31                    |
| 0.12                     | 0.24                        | 0.62                    |
| 0.24                     | 0.24                        | 2.49                    |

**(a) What is the rate law?**

(Use \( k \) for the rate constant.)

\[ \text{Rate} = k[\text{NO}]^2[\text{Cl}_2] \]

**(b) What is the value of the rate constant?**

The units for the rate constant are \(\frac{L^2}{\text{mol}^2 \cdot \text{min}}\).

[The space for the value is left blank for calculation.]
