Consider a binary mixture composed of -hexane and -octane; this Demonstration uses Henley and Seader's data to plot the enthalpy versus composition diagram at 101 kPa. The curves are the liquid (, in blue) and vapor (, in magenta) enthalpy versus the liquid () and vapor () mole fraction curves. Click either curve to place the locator there. Then the vapor-liquid and enthalpy data is displayed as text at the bottom and the tie line is plotted in red.
