Question

According to fundamental thermodynamic definitions and exact Maxwell relations, which of the following partial derivative equations correctly describes the behavior of the Gibbs Free Energy ($G$)?

Prashant Kotian · Accepted Answer

Correct answer: A. The fundamental equation for Gibbs Free Energy is . Holding pressure constant (), we get the partial derivative . This physically explains why always decreases as temperature increases (since entropy is positive).
