Which of the following set of conditions is favourable for the maximum yield of ammonia by Haber's process ?
Correct answer: C. High pressure, high reactants concentration, low temperature
- A. High pressure, low reactants concentration, high temperature
- B. High pressure, low reactants concentration, low temperature
- C. High pressure, high reactants concentration, low temperature
- D. Low pressure, high reactants concentration, low temperature
Explanation
Ammonia synthesis is favoured by high pressure, high reactant concentration, and low temperature because the reaction forms fewer gas moles and is exothermic. Industrial plants use a moderately high temperature as a compromise so the reaction remains fast enough.
