Question

State the condition under which Hydrogen reacts with Nitrogen.

Answer 1

1. Under specific conditions of temperature which is around 473K-673K (200- 400°C), pressure such as 250 atmospheres (25331250 Pascal), and catalyst ( usually Iron ($\mathrm{Fe}$)), one mole of Nitrogen($\mathrm{N}$) combines with three moles of Hydrogen($\mathrm{H}$) to give Ammonia ( ${\mathrm{NH}}_3$) which is a pungent smelling and colorless gas.
2. This process is known as Haber's process.
3. Reaction involved- $\underset{\mathrm{nitrogen}}{{\mathrm{N}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{hydrogen}}{3{\mathrm{H}}_2\left(\mathrm{g}\right)}\underset{{450}^{\mathrm{o}}\mathrm{C},\mathrm{Fe}}{\to }\underset{\mathrm{ammonia}}{2{\mathrm{NH}}_3\left(\mathrm{g}\right)}$
