NEET Chemistry Gibbs Free Energy MCQ Question
Which of the following statements about Gibbs Free Energy (∆rG°) is correct?
A negative value of ∆rG° indicates that the reaction is spontaneous at constant temperature and pressure.
A positive value of ∆rG° means the reaction will always occur spontaneously.
∆rG° can never be zero for any reaction at equilibrium.
∆rG° is independent of temperature and pressure conditions.
Correct Answer
Detailed Explanation
A negative value of Gibbs Free Energy indicates that the reaction is spontaneous under the given conditions, as indicated by the relationship between Gibbs Free Energy and reaction spontaneity.
