ChE 263 Assignment #19 (Mathcad ® HW #7) Note: This homework assignment is to be done using Mathcad ® . When a vapor is in equilibrium with a liquid, there is no net transfer of mass between the vapor and liquid, and compositions (vapor and liquid) are constant with time. For simple (ideal) systems, Raoult’s law may be used to calculate the compositions, temperature, and pressure of the system. However, for non-ideal systems, a modified version of Raoult’s law may be used. For a non-ideal binary system (i.e. consisting of only 2 components, we’ll call them components 0 and 1), the following variables are important: where: y 0 = mole fraction of species 0 in the vapor phase y 1 = mole fraction of species 1 in the vapor phase x 0 = mole fraction of species 0 in the liquid phase x 1 = mole fraction of species 1 in the liquid phase P vp ,0 = vapor pressure of species 0 P vp ,1 = vapor pressure of species 1 0 = activity coefficient of species 0 1 = activity coefficient of species 1
