The conditions actually used in the Haber process are about
Correct answer: C. 450 degrees Celsius and 200 atmospheres
- A. 1000 degrees Celsius and 1 atmosphere
- B. 25 degrees Celsius and 1000 atmospheres
- C. 450 degrees Celsius and 200 atmospheres
- D. 450 degrees Celsius and 1 atmosphere
Explanation
A moderately high temperature is a compromise, since a low temperature would give a better yield but far too slowly for industry, while high pressure genuinely improves the yield and is limited only by the cost and strength of the plant. Ammonia is removed by liquefaction and the unreacted gases are recycled, so the overall conversion is high even though each pass is poor.

About Haber's Process
Haber's process produces ammonia by reacting nitrogen with hydrogen in a reversible, exothermic equilibrium. The topic covers the iron catalyst, operating temperature and pressure, Le Chatelier's principle, the compromise between reaction rate and equilibrium yield, and the removal and recycling of ammonia and unreacted gases.
