Please answer draw and write out all the steps. Thank you.
Two species A and B are at VLE. Their saturated vapor pressures follow Antoine Equations:
ln(PAsat/kPa) = 14.3 - 2750/(T/°C - 228), ln(PBsat/kPa) = 15.4 - 3000/(T/°C - 200)
The activity coefficients of species A and B can be expressed as:
ln γA = CxB^2, ln γB = CxA^2 where C = 3.00 - 0.02T (in °C)
Find the equilibrium temperature and liquid phase composition of A and B if P = 50 kPa and yA = 0.6.
