NEET Physics Entropy Assertion Reason Question

Type: Assertion Reason-assertion-Medium-Class 11

Assertion (A): Gibbs energy is the sole determinant of spontaneity for chemical reactions. | Reason (R): Total entropy change alone can determine the direction of spontaneous change in closed and open systems.

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

A is false but R is true.

Correct Answer

Option C

Detailed Explanation

Gibbs energy involves both enthalpy and entropy to determine spontaneity, while total entropy change alone cannot determine spontaneity in closed and open systems.
