A system of acetone-benzene at 318.15 K forms a non-ideal solution. Its vapor-liquid equilibrium is given in Figure Q3 for partial and total vapor pressures of the system vs mole fraction of acetone in liquid phase, xAc,I. Show the partial pressure curve of the acetone, PAc, partial pressure curve of the benzene, PBen and the total pressure curve on the Figure Q3. a) Determine the vapor pressures of acetone and benzene and show on the Figure. b) If the composition of the solution is 0.3 mole fraction of acetone, xAc,l, determine the partial pressures of acetone and benzene and calculate the total pressure of the solution. If the composition of the solution is 0.3 mole fraction of acetone, calculate the activity and activity coefficient of the acetone and benzene, according to Convention I and c) Convention II assuming that acetone is solute. d) If the composition of the solution is 0.3 mole fraction of benzene, calculate the activity and activity coefficient of the acetone and benzene, according to Convention I and Convention II assuming that benzene is solute. 140 120 100 80 60 40 20 0,1 0,2 0,3 0,4 0,5 0,6 0,7 0,8 0,9 1 Mole fraction of Acetone in liq., XAC1 Figur Q3.
