Which of the following statements correctly describes the relationship between enthalpy (ΔH), entropy (ΔS), and Gibbs free energy (ΔG)?
Correct: B
The Gibbs free energy equation is ΔG = ΔH - TΔS, where ΔG is the Gibbs free energy change, ΔH is the enthalpy change, T is the absolute temperature, and ΔS is the entropy change. This equation describes the spontaneity of a reaction.
