Haber Process - Ammonia [Exothermic]

Uses -

1. Fertilizer
2. Cleaning
3. Water treatment

Process -

1. H2 and N2 = Obtained from natural gas [methane] and air
2. Gasses are compressed to 200 atm
3. Gasses are taken to tank with layers of catalytic iron beds at 450 degrees
4. N2 (g) + 3H2 (g) ⇌ 2NH3 (g)
5. Unreacted N2 and H2 are recycled
6. Ammonia is cooled, liquefied and removed

Economic considerations -

1. Lots of heat and pressure which is expensive
2. Raw materials are easily obtainable

Temperature - 450 degrees

1. Lower temperature favours forward reaction → More products or ammonia BUT at lower temperatures the rate is too slow and hence 450 degrees is a compromise
