Assertion : According to Le-Chatelier's principle addition of heat to an equilibrium solid \(\rightleftharpoons\) liquid results in decrease in the amount of solid.
Reason : Reaction is endothermic, so on heating forward reaction is favoured.
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.
Solution
Solid + heat $\rightleftharpoons$ liquid. So on heating forward reaction is favoured and amount of solid will decrease.
