Question

According to Le-Chatelier?? principle addition of heat to an equilibrium solid ? liquid results in decrease in the amount of solid. Reaction is endothermic, so on heating forward reaction is favoured.

• 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: (A)

If both assertion and reason are true and reason is the correct explanation of assertion

Answer 2

Solid + heat $\rightleftharpoons$ liquid. So on heating forward reaction is favoured and amount of solid will decrease.
