Identify the CORRECT option required for the maximum yield of ammonia by Haber's Process:
Correct answer: A. High pressure, low temperature, continual removal of ammonia
- A. High pressure, low temperature, continual removal of ammonia
- B. Low pressure, low temperature, continual removal of ammonia
- C. High pressure, high temperature, continual removal of ammonia
- D. High pressure, low temperature, continual addition of ammonia
Explanation
The maximum yield of ammonia in the Haber process is theoretically limited to about 15% under typical conditions of high temperature (around 400-500°C) and high pressure (150-300 atmospheres). However, in practice, the yield is often lower due to factors like equilibrium constraints and reaction kinetics. To increase the yield, unreacted gases can be recycled back into the reactor, making the process more efficient.

About Chemical Equilibrium
Reversible reactions reach dynamic equilibrium when forward and reverse rates become equal, and Le Chatelier's principle predicts the effect of changing concentration, pressure or temperature. The chapter also covers solubility product, the common ion effect, buffer action and the conditions used in Haber's process, with equilibrium shifts distinguished from changes in the equilibrium constant.
