Assertion : Ice water, if pressure is applied water will evaporate. Reason : Increases of pressure pushes the equilibrium towards the side in which number of gaseous molecule increases.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion
  3. CIf assertion is true but reason is false
  4. DIf both assertion and reason are false.

Correct answer

D. If both assertion and reason are false.

Step-by-step solution

Increase in pressure favours melting of ice into water because at higher pressure melting point of ice is lowered. According to Le-Chatelier's principle, if pressure is increased the equilibrium will shift in direction which produces smaller number of moles.
