How is ammonia manufactured by Haber process? – InterviewSolution

1.	How is ammonia manufactured by Haber process?
Answer» On the large scale, ammonia is prepared by direct combination of dinitrogen and dihydrogen by Haber process. In this process, dinitrogen reacts with dihydrogen under high pressure of 200 × 10⁵ Pa (200 atm) and temperature around 700 K to produce ammonia. N_2(g) + 2H_2(g) ⇌ 2NH_3(g) ; Δ_f H° = -46.1 kJ mol^-1 Iron oxide with trace amounts of K₂O and Al₂O₃is used as catalyst in Haber process. High pressure favours the formation of ammonia as equilibrium is attained rapidly under these conditions.
