Question
An isolated system comprises the liquid in equilibrium with vapours. At this stage, the molar entropy of the vapour is
Answer: B
💡 Solution & Explanation
Vapour phase is inherently much more disordered and random compared to the liquid phase. Therefore, the molar entropy of vapour is always higher than that of liquid, even at equilibrium.
