Chemical Kinetics

Ammonia and oxygen react at high temperature as

\(4 \mathrm{NH}_{3(\mathrm{~g})}+5 \mathrm{O}_{2(\mathrm{~g})} \longrightarrow 4 \mathrm{NO}_{(\mathrm{g})}+6 \mathrm{H}_2 \mathrm{O}_{(\mathrm{g})} \text {. }\)

If rate of formation of \(\mathrm{NO}_{(\mathrm{g})}\) is \(3.6 \times 10^{-3} \mathrm{~mol} \mathrm{~L}^{-1} \mathrm{~s}^{-1}\) then rate of disappearance of ammonia is
