Question

Substance X has a heat of vaporization of 55.4 kJ/mol at its normal boiling point (423°C). For the process X(l) $\rightarrow$ X(g) at 1 atm and 423°C, calculate the value of: -$\Delta$S_univ

Quizplus · Accepted Answer

At the boiling point, the system is at equilibrium, so the entropy change of the universe (ΔSuniv) is zero.
