The following data was obtained for chemical reaction given below at $975 \mathrm{K}$.

$2{\mathrm{NO}}_{\left(\mathrm{g}\right)}+2{\mathrm{H}}_{2( \mathrm{g})}\to {\mathrm{N}}_{2( \mathrm{g})}+2{\mathrm{H}}_2{\mathrm{O}}_{\left(\mathrm{g}\right)}$

$\begin{array}{cccc} & \left[\mathrm{NO}\right]& \left[{\mathrm{H}}_2\right]& \mathrm{Rate}\\ & \text{ mol }{\mathrm{L}}^{-1}& \text{ mol }{\mathrm{L}}^{-1}& {\mathrm{molL}}^{-1}{ \mathrm{s}}^{-1}\\ \left(A\right)& 8\times {10}^{-5}& 8\times {10}^{-5}& 7\times {10}^{-9}\\ \left(B\right)& 24\times {10}^{-5}& 8\times {10}^{-5}& 2.1\times {10}^{-8}\\ \left(C\right)& 24\times {10}^{-5}& 32\times {10}^{-5}& 8.4\times {10}^{-8}\end{array}$

The order of the reaction with respect to $\mathrm{NO}$_____ is [Integer answer]
