1.1 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/C - 32.445)log10P2sat/bar = 3.96988 - 1203.526/(T/C - 50.287)GE/RT = 1.888X1X2MM1 = 58.0791 g.mol-1MM2 = 84.1595 g.mol-1Now answer the following questions:1. Estimate the bubble point temperature of a liquid mixture of 57.6 mol % aceton (1)+ cyclohexane (2) at P = 0.351 bar.2. What is the liquid composition of an acetone (1) + cyclohexane (2) mixture whiresults in a saturated pressure of 0.217 bar at T = 298.15 K? 3. What are the values of Iny₁ and Iny2? Explain. Plot the excess Gibbs free ener as a function of the mole fraction of acetone.4. Find the system temperature which results in a vapour phase composition of 7 mol % acetone (1) + cyclohexane (2) at P = 0.346 bar.

Question
1.1 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/C - 32.445)
log10P2sat/bar = 3.96988 - 1203.526/(T/C - 50.287)
GE/RT = 1.888X1X2
MM1 = 58.0791 g.mol-1
MM2 = 84.1595 g.mol-1
Now answer the following questions:
1. Estimate the bubble point temperature of a liquid mixture of 57.6 mol % aceton (1)+ cyclohexane (2) at P = 0.351 bar.
2. What is the liquid composition of an acetone (1) + cyclohexane (2) mixture whi
results in a saturated pressure of 0.217 bar at T = 298.15 K? 3. What are the values of Iny₁ and Iny2? Explain. Plot the excess Gibbs free ener as a function of the mole fraction of acetone.
4. Find the system temperature which results in a vapour phase composition of 7 mol % acetone (1) + cyclohexane (2) at P = 0.346 bar.
