Consider a low-vapor pressure binary system (consisting of species 1 and 2) in vapor-liquid equilibrium. Let a = The liquid phase is an equimolar mixture. If the system follows the modified Raoult's law, prove that the P, sat is given by: psat t P.sat P x1(V1 + Y2 + where y = activity coefficient, psat = pures pecies vapor pressure of Species 1 P= total vapor pressure x = mole fraction in liquid phase
