NEET Chemistry Entropy Assertion Reason Question
Assertion (A): For an irreversible expansion of an ideal gas under isothermal conditions, the total entropy change (∆S total) is non-zero. | Reason (R): The degree of randomness or disorder in an isolated system is directly related to its entropy.
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, but R is true.
Correct Answer
Detailed Explanation
The assertion is true because irreversible processes result in a net increase in entropy. The reason correctly explains this by associating entropy with the degree of disorder.
