The following data was obtained for chemical reaction given below at $\displaystyle 975$ K .
$$2 \mathrm{NO}_{(\mathrm{g})}+2 \mathrm{H}_{2(\mathrm{~g})} \rightarrow \mathrm{N}_{2(\mathrm{~g})}+2 \mathrm{H}_2 \mathrm{O}_{(\mathrm{g})}
$$
The order of the reaction with respect to NO is \_\_\_\_. [Integer answer]
| [NO] | $\displaystyle \left[\mathrm{H}_2\right]$ | Rate | |
| $\displaystyle \mathrm{mol} \mathrm{L}^{-1}$ | $\displaystyle \mathrm{mol} \mathrm{L}^{-1}$ | $\displaystyle \mathrm{mol} \mathrm{L}^{-1} \mathrm{s}^{-1}$ | |
| (A) | $\displaystyle 8 \times 10^{-5}$ | $\displaystyle 8 \times 10^{-5}$ | $\displaystyle 7 \times 10^{-9}$ |
| (B) | $\displaystyle 24 \times 10^{-5}$ | $\displaystyle 8 \times 10^{-5}$ | $\displaystyle 2.1 \times 10^{-8}$ |
| (C) | $\displaystyle 24 \times 10^{-5}$ | $\displaystyle 32 \times 10^{-5}$ | $\displaystyle 8.4 \times 10^{-8}$ |
