Solution - How is ammonia manufactured industrially? - CBSE (Science) Class 12 - Chemistry

Question

How is ammonia manufactured industrially?

Solution 1

Commercially, by Haber’s process.

`N_2(g) + 3H_2(g) ⇌ 2NH_3(g)                           triangle_fH^@ = -46.1 kJ mol^(-1)`

iron oxide, K2O, Al20The optimum conditions for the production of NH3 are pressure of 200 atm and temperature of 100K

Solution 2

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

Is there an error in this question or solution?
