www.cpp.eduxA = mole fraction of A in the liquid phase For some problems, the use of solute-free basis can simplify the expressions. The solute-free concentrations are defined as: XA = 1 A A x −x = mole fraction of A in the liquid mole fraction of non-A components in the liquid (5.2-3a) YA = 1 A A y −y = mole fraction of A in the vapor mole fraction ...
