Consider vapour-liquid equilibrium for the acetone (1) + cyclohexane (2) system. The following is known about this system: log10P1sat/bar = 4.42448 – 1312.253/(T/K – 32.445) log10P2sat/bar = 3.96988 – 1203.526/(T/K – 50.287) GE/RT = 1.888x1x2 MM1 = 58.0791 g.mol-1 MM2 = 84.1595 g.mol-1 Now answer the following questions 1.2.1. Estimate the bubble point temperature of a liquid mixture of 57.6 mol % acetone (1) + cyclohexane (2) at P = 0.351 bar. 1.2.2. What is the liquid composition of an acetone (1) + cyclohexane (2) mixture which results in a saturated pressure of 0.217 bar at T = 298.15 K? 1.2.3. What are the values of lnγ1∞ and lnγ2∞? Explain. Plot the excess Gibbs free energy as a function of the mole fraction of acetone. 1.2.4. Find the system temperature which results in a vapour phase composition of 71.6 mol % acetone (1) + cyclohexane (2)
