The enthalpy of fusion for benzene is 127.34 kJ/kg,and its melting point is 5.49 $\circ$ C.Estimate $\Delta$G $\circ$ when 1.00 mole of benzene melts at 25.00 $\circ$ C.

Question

Quizplus · Accepted Answer

The Gibbs free energy change (ΔG) for melting at a temperature different from the melting point can be estimated using ΔG = ΔH - TΔS. Since melting is spontaneous at the melting point, ΔG = 0 at 5.49°C. At 25°C, ΔG can be estimated using the enthalpy of fusion and the temperature difference.
