NEET Physics Entropy Assertion Reason Question
Assertion (A): Gibbs energy change (ΔG) is the net energy available to do useful work.
Reason (R): For a spontaneous process, the change in Gibbs energy (ΔG) is less than zero.
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
According to the NCERT context, ΔG is the net energy available to do useful work and for a spontaneous process, ΔG < 0, making R the correct explanation for A.
