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. Geankoplis, Christie John, Hersel, A. Allen, Lepek, Daniel H..
