Question

Name the process used to manufacture Ammonia gas commercially.

Answer 1

Ammonia:

• Ammonia is a compound of nitrogen and hydrogen with the formula ${\mathrm{NH}}_3$.
• Ammonia is a colorless, poisonous gas with a sharp pungent suffocating odor.
• It is naturally produced by the decay of plant and animal matter.
• It is commercially prepared by Haber's process.
• In this process atmospheric nitrogen (${\mathrm{N}}_2$) is converted to ammonia (${\mathrm{NH}}_3$) by reacting it with hydrogen (${\mathrm{H}}_2$).
• The reaction is as : ${\mathrm{N}}_2+3{\mathrm{H}}_2\to 2{\mathrm{NH}}_3$
• In this process Iron is used as a catalyst, and during the whole process temperature is maintained around 400 – 450^oC and a pressure of 150 – 200 atm.
