Question

The normal boiling point of acetic acid is 118.1°C.If a sample of the acetic acid is at 125.2°C, Predict the signs of $\Delta$H, $\Delta$S, and $\Delta$G for the boiling process at this temperature. A)($\Delta$H > 0, $\Delta$S > 0, $\Delta$G < 0) B)($\Delta$H > 0, $\Delta$S > 0, $\Delta$G > 0) C)($\Delta$H > 0, $\Delta$S < 0, $\Delta$G < 0) D)($\Delta$H < 0, $\Delta$S > 0, $\Delta$G > 0) E)($\Delta$H < 0, $\Delta$S < 0, $\Delta$G > 0)

Quizplus · Accepted Answer

Boiling is an endothermic process, so $\Delta$H > 0. Boiling increases entropy, so $\Delta$S > 0. At a temperature above the normal boiling point, $\Delta$G > 0.
