Consider a reversible thermodynamic process involving one mole of ideal gas represented by a line on the $P-V$ diagram connecting two states X (4 bar, 1 L, $\text{T}_1$) and Y (1 bar, 2 L, $\text{T}_2$) as shown in the figure:

During the process the change in temperature (in K) as a function of volume (in L) is best represented as:

X, Y, and Z are three volatile liquids, which when mixed make an ideal solution. At a given temperature $\text{T}_0$, the constituents X, Y, and Z have pure vapour pressures in the ratio 3:2:1. A mixture prepared with mole-fractions of X, Y, and Z in the ratio 1:2:3 starts to boil at temperature $\text{T}_0$ at 1.5 atm pressure. At temperature $\text{T}_0$, the partial vapour pressure (in atm) of Y is:
