$R = k {\left[N O\right]}^{2} {\left[{H}_{2}\right]}^{1}$

$\setminus \textcolor{\in \mathrm{di} a n red}{\setminus \textrm{B y t h e w a y - - t h e e q u a t i o n h a s a t y p o , i t s h o \underline{d} b e}}$
$\setminus \textcolor{l i g h t c \mathmr{and} a l}{2 N O + 2 {H}_{2} \setminus \rightarrow {N}_{2} + 2 {H}_{2} O}$

#### Explanation:

Given ${\left[N O\right]}^{m} {\left[{H}_{2}\right]}^{n}$, I found $m = 2$ (Khan Academy method)
and $n = 1$. Therefore the rate law is

$R = k {\left[N O\right]}^{2} {\left[{H}_{2}\right]}^{1}$
