A) ΔSsub = ΔSfusion + ΔSvaporization
B) ΔSsub < ΔSvaporization
C) ΔSsub = ΔSfusion - ΔSvaporization
D) ΔSsub < (ΔSfusion + ΔSvaporization)

Quizplus · Accepted Answer

The molar entropy of sublimation (ΔSsub) is the sum of the molar entropy of fusion (ΔSfusion) and the molar entropy of vaporization (ΔSvaporization), as sublimation is the direct transition from solid to gas.
