For the reaction; $4 \mathrm{NH}_{3(\mathrm{~g})}+5 \mathrm{O}_{2(\mathrm{~g})} \longrightarrow 4 \mathrm{NO}_{(\mathrm{g})}+6 \mathrm{H}_{2} \mathrm{O}_{(\mathrm{g})}$, the
rate of reaction in terms of disappearance of $\mathrm{NH}_{3}$ is $-\frac{d\left[\mathrm{NH}_{3}\right]}{d t}$, then write the rate expression in terms of concentration of $\mathrm{O}_{2}, \mathrm{NO}$ and $\mathrm{H}_{2} \mathrm{O}$
