Assertion: Water in liquid state is more stable than ice at room temperature.
Reason: Water in liquid form has higher entropy than ice.
(a) If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
(b) If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
(c) If the Assertion is correct but Reason is incorrect.
(d) If both the Assertion and Reason are incorrect.
(e) If the Assertion is incorrect but the Reason is correct.
(a) If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
Explanation:
At room temperature water is more stable because ice will tend to melt at room temperature. So, A is true. But water will have larger entropy than ice because ice absorbs heat to be converted into water.
ΔS = ΔH/T
We know that greater the entropy, greater the stability. Hence, water is more stable than ice. Both A and R is true and R explains A.
