In a given system, water and ice are in equilibrium, if the pressure is applied to the system then:
Correct answer: C. More ice is melted.
- A. More ice is formed.
- B. Amount of ice and water will remain the same.
- C. More ice is melted.
- D. Both A and B.
Explanation
Ice ⇌ liquid waterAccording to Le-Chatelier principle, increase in pressure move reaction in direction in which volume is less. Ice has 9% more volume than liquid water. So, increase in pressure will convert ice (more volume) into liquid water (less volume). So, by increasing pressure ice starts to melt.

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.
