This Demonstration shows how the fugacities of each component in an ideal binary mixture, benzene (
B
) and toluene (
T
), change with temperature and molar composition at constant pressure. Use the sliders to vary the temperature and overall mole fraction of benzene. Use the buttons to view the temperature-composition diagram

, a fugacity-temperature plot, or to view both plots at once. The point on the
T
xy
diagram corresponds to the two fugacity values in the fugacity plot.
