Substance X has a heat of vaporization of 55.9 kJ/mol at its normal boiling point (423°C).For the process X(l)$\to$ X(g)at 1 atm and 423°C calculate the value of $\Delta$S_univ.

Question

Quizplus · Accepted Answer

The change in the Gibbs free energy (ΔG) for a process at its normal boiling point and 1 atm is zero because the system is in equilibrium. Since ΔG = ΔH - TΔS, and ΔG is zero, the change in entropy of the universe (ΔSuniv) is also zero because the process is reversible at this condition.
