SUMMARY
The discussion centers on the relationship between Gibbs free energy and entropy in benzene across its three phases: solid, liquid, and gas. It establishes that the entropy values follow the order S(gas) > S(liquid) > S(solid), supported by the equation (dG/dT)_P = −S. The analysis indicates that as temperature increases, the Gibbs free energy decreases, and the slopes of the tangent lines in the G vs T graph become steeper from solid to gas, confirming the increasing entropy values.
