Question

Assertion: Ice $\rightleftharpoons$ 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.

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (D)

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.
