NEET Chemistry Entropy Assertion Reason Question
Type: Assertion Reason-assertion-Hard-Class 11
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.
A
Both (A) and (R) are true and (R) is the correct explanation of (A).
B
Both (A) and (R) are true but (R) is not the correct explanation of (A).
C
(A) is true but (R) is false.
D
