When liquid and vapour phases of one component system are in equilibrium (at a given temperature and pressure), the molar free energy is
A. More in vapour phase
B. More in liquid phase
C. Same in both the phases
D. Replaced by chemical potential which is more in vapour phase
Answer: Option C
Solution(By Examveda Team)
If the liquid and vapor are pure, in that they consist of only one molecular component and no impurities, then the equilibrium state between the two phases is described by the following equations:Pliq = pvap, TLIQ = TVAP, GLIQ = GVAP.
