NEET Chemistry Gibbs Free Energy Assertion Reason Question

Type: Assertion Reason-assertion-Medium-Class 11

Assertion (A): A reaction with a negative Gibbs free energy change (ΔG) is spontaneous at a given temperature. | Reason (R): A positive ΔH and negative ΔS always lead to a negative ΔG at any temperature.

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.

Correct Answer

Option C

Detailed Explanation

A negative ΔG indicates spontaneity, but a positive ΔH and negative ΔS would result in a positive ΔG at all temperatures, not a negative one.
