Ammonia and oxygen react at high temperature as $$4{\mathrm{NH}}_{3(\mathrm{g})}+5{\mathrm{O}}_{2(\mathrm{g})}⟶{\mathrm{NO}}_{(\mathrm{g})}+6{\mathrm{H}}_2{\mathrm{O}}_{(\mathrm{g})}\text{. }$$ 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
