In Haber's process, the volume percentage of ammonia in equilibrium mixture is?
Correct answer: C. 35%
- A. 30%
- B. 32%
- C. 35%
- D. 33%
Explanation
Option A is incorrect because the volume percentage of ammonia in the reaction mixture is not 30%. Option B is incorrect because the volume percentage of ammonia in the equilibrium reaction mixture is not 32%. Option: C The exact volume percentage of ammonia in Haber's process depends upon the reaction conditions such as pressure, temperature, etc. They comprise 400_ 450° C is a compromise temperature producing a reasonably high portion of ammonia in an equilibrium mixture (even if it is only 15%) but in a very short time. Option D is incorrect because the volume percentage of ammonia in the equilibrium mixture is not 33%.

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.
