1.	Ammonia is manufacture by Haber’s process, which involves the combination of nitrogen and hydrogen.(i) What is the ratio of nitrogen to hydrogen by volume? (ii) What is the source of nitrogen used in the process? (iii) Give the following features of Haber’s process.(1) Approximate temperature(2) approximate pressure(3) Catalyst(iv) How is the ammonia formed separated from the nitrogen and hydrogen?
Answer» (i) 1 : 3 (ii) From air (iii) (1) 450 – 500°C (2) 200 – 900 atmosphere. (3) Finely divided iron with little of molybdenum. (iv) (1) By passing through a condenser where ammonia liquefies. (2) Dissolving in water. (3) Passing though sulphuric acid to form ammonium sulphate which is directly used as fertilizer.
