In a given system water and ice are in equilibrium if pressure is applied to the above system then:
Correct answer: B. More ice is melted
- A. More ice is formed
- B. More ice is melted
- C. Amount of ice and water remains constant
- D. None of these
Explanation
More ice is melted: If the pressure is increased to a very high level, the equilibrium may shift to the point where all of the water is in the form of ice. This is because the pressure is so high that it is no longer possible for any of the water molecules to exist as a gas.

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.
