NEET Chemistry Entropy Assertion Reason Question
Assertion (A): Entropy change can distinguish between reversible and irreversible processes for an ideal gas.
Reason (R): Entropy is a measure of the degree of randomness or disorder in the system.
Both (A) and (R) are true and (R) is the correct explanation of (A).
Both (A) and (R) are true but (R) is not the correct explanation of (A).
(A) is true but (R) is false.
(A) is false.
Correct Answer
Detailed Explanation
The NCERT context states that entropy change, ∆S, distinguishes between reversible and irreversible processes, and entropy is a measure of disorder, explaining why ∆S differs.
