Question
How is ammonia manufactured industrially?
Solution 1
Ammonia is prepared on a large-scale by the Haber’s process.
`N_2(g) + 3H_2(g) ⇌ 2NH_3(g) triangle_fH^@ = -46.1 kJmol`
The optimum conditions for manufacturing ammonia are:
(i) Pressure (around 200 × 105 Pa)
(ii) Temperature (700 K)
(iii) Catalyst such as iron oxide with small amounts of Al2O3 and K2O
Solution 2
Commercially, by Haber’s process.
`N_2(g) + 3H_2(g) ⇌ 2NH_3(g) triangle_fH^@ = -46.1 kJ mol^(-1)`
iron oxide, K2O, Al203 The optimum conditions for the production of NH3 are pressure of 200 atm and temperature of 100K
