Question

The Haber's process of the manufacture of ammonia is usually carried out at about ${500}^{o}C$. If a temperature of about ${250}^{o}C$ was used instead of ${500}^{o}C$.

• A. Ammonia would not be formed at all
• B. The percentage of ammonia in the equilibrium mixture would be to low
• C. A catalyst would be no use at all this temperature
• D. The rate formation would be to slow

Answer 1

The correct option is A Ammonia would not be formed at all

The optimum conditions for the productions of ammonia are a pressure of 200 atm and a temperature of about 700 K.
Below this temperature ammonia would not be formed at all.
Option A
