What are the conditions that help in raising the yield of ammonia?
To raise the yield of ammonia, the industrial process designed to operate under conditions favoring product formation:
- High pressures (concentrations) of reactants used, ~150−250 atm, to shift the equilibrium right, favoring product formation.
- Ammonia is continually removed (collected) from the equilibrium mixture during the process, lowering its concentration and also shifting the equilibrium right.
- Although low temperatures favor product formation for this exothermic process, the reaction rate at low temperatures is inefficiently slow. A catalyst used to accelerate the reaction to reasonable rates at relatively moderate temperatures (400−500 °C)
