Q62 / 180 · AIIMS 2008 · Chemistry

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.

  • Correct answer
    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.

Solution

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

Hence, the correct answer is option: 'A'.
