4. A liquid mixture that include %70 n-pentane and %30 n-hexane is vaporized in a semi-batch
distiller. The equilibrium mole fraction balance between the liquid and vapor is y=ax/(x+b).
Here x and y are respectively the mole fractions of n-pentane at liquid and vapor phase.
a) If x=1 then what is the value of y? Find the relationship between a and b?
b) At 46 °C a liquid phase including %70 n-pentane and %30 n-hexane is at equilibrium with
its vapor phase. Then find the vapor mole fraction of n-pentane by using Rault’s law and
Anotine equation. Also determine the coefficients a and b for the relations of x and y.
c) Find the relationship between the remaining liquid in distiller(L) and mole fraction of
pentane that in liquid. (xf)
d) If 75% of liquid evaporates find the value of xf ?
