A mixture of 100 mol containing 60 mol % n-pentane and 40 mol % n-heptane is vaporized at 101.32 kPa abs pressure until 40 mol of vapor and 60 mol of liquid in equilibrium with each other are produced. This occurs in a single-stage system and the vapor and liquid are kept in contact with each other until vaporization is complete. The equilibrium data are given in Example 26.3-2. Calculate the composition of the vapor and the liquid.

Question
A mixture of
100 mol containing 60 mol % n-pentane and 40 mol % n-heptane is
vaporized at 101.32 kPa abs pressure until 40 mol of vapor and 60
mol of liquid in equilibrium with each other are produced. This
occurs in a single-stage system and the vapor and liquid are kept in
contact with each other until vaporization is complete. The
equilibrium data are given in Example 26.3-2. Calculate the
composition of the vapor and the liquid.
Transcribed Image Text:and the composition of the liquid left? The equilibrium
data are as follows, where x and y are mole fractions of n-pentane:
