Which of the following change will favour the formation of adequate amount ammonia at equilibrium in the reaction given below:
Correct answer: B. By increasing pressure.
- A. By decreasing pressure.
- B. By increasing pressure.
- C. By adding ammonia.
- D. By removing nitrogen.
Explanation
According to le Chateliers principle in order to get more ammonia in equilium mixture, high preesure is needed.Increasing the pressure will increasing the chances of hitting and reaction of molecules.

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.
