Vapor-liquid equilibrium diagram ideal mixture

The following plot shows the vapor-liquid phase diagram for a binary ideal mixture (components: A and B). The vapor pressures of the pure substances are [math]p_A^*[/math] and [math]p_B^*[/math], respectively.

The red curve shows the vapor pressure of the mixture [math]p[/math] as a function of the mole fraction of A in the liquid [math]x_A^l[/math]:

[math]p=p_A^*+(p_B^*-p_B^*)x_A^l[/math]

In the example below [math]p_A^*=1[/math] (a.u.) and the [math]p_B^*/p_A^*[/math] ratio can be changed moving the slider below.
