Vapor-liquid equilibrium diagram ideal mixture

The following plot shows the vapor-liquid phase diagram for a binary mixture (A and B). The vapor pressures of the pure substances are [math]P_A^*[/math] and [math]P_B^*[/math], respectively. In the example below [math]P_A^*=1 (in a.u.)[/math] and [math]ratio=P_B^*/P_A^*[/math].
