Q2. Which process used to manufacture urea?
Ans. 
Urea is manufactured through the Haber-Bosch process.
• The Haber-Bosch process is a chemical reaction that combines nitrogen and hydrogen to produce ammonia.

• The ammonia is then reacted with carbon dioxide to form urea.

• The process involves high pressure and temperature conditions.

• The reaction is catalyzed by iron-based catalysts.

• The urea produced is used as a fertilizer and in the production of plastics, resins, and adhes
