Question

The precise number of moles of nitrogen molecules ($\mathrm{N}_2$) strictly required to produce exactly $50 \mathrm{~moles}$ of ammonia through Haber's process is

Professor PC Thomas Classes · Answer

(a) : The balanced chemical equation for Haber's process is $\mathrm{N}_2(g) + 3\mathrm{H}_2(g) \rightleftharpoons 2\mathrm{NH}_3(g)$. From the stoichiometry of the reaction, it is clear that 1 mole of $\mathrm{N}_2$ produces 2 moles of $\mathrm{NH}_3$. Therefore, to produce 50 moles of $\mathrm{NH}_3$, the required moles of $\mathrm{N}_2$ will be $\frac{50}{2} = 25 \mathrm{~moles}$.
