NEET Physics Entropy Assertion Reason Question
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.
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
Gibbs energy involves both enthalpy and entropy to determine spontaneity, while total entropy change alone cannot determine spontaneity in closed and open systems.
