In Haber's process, ammonia is synthesized as

${\mathrm{\text{N}}}_2+3{\mathrm{\text{H}}}_2\frac{\mathrm{\text{F}}\mathrm{\text{e}},\mathrm{\text{M}}\mathrm{\text{o}},300\mathrm{\text{℃}}}{\mathrm{\text{H}}\mathrm{\text{i}}\mathrm{\text{g}}\mathrm{\text{h}}\mathrm{\text{P}}\mathrm{\text{r}}\mathrm{\text{e}}\mathrm{\text{s}}\mathrm{\text{s}}\mathrm{\text{u}}\mathrm{\text{r}}\mathrm{\text{e}}}\to 2\mathrm{\text{N}}{\mathrm{\text{H}}}_3$

Rate of synthesis of ammonia =$\frac{60}{60}$

$=\text{1 mol/min}$

$\therefore$Rate of disappearance of nitrogen, i.e.,

$\frac{-\text{d}\left[{\text{N}}_2\right]}{\text{d}\text{t}}=\frac{1}{2}\frac{\text{d}\left[\text{N}{\text{H}}_3\right]}{\text{d}\text{t}}$

$=\text{0}\text{.5 mol/min}$
