NEET Chemistry Gibbs Free Energy Assertion Reason Question
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.
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
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.
