Q1 An ideal solution system consists of one mole of n-pentaneand one mole of n-hexane is heated to 150° F.

Calculate the following;

1.Dew point pressure.

2. Composition of the liquid at the dew point pressure.

3. Bubble point pressure.

4. Composition of vapor at the bubble point pressure.

5. Composition of the liquid and the vapor if the systempressure is 50 psia.

6. Plot the composition of n-pentne on the x-axis versus thepressure on the y-axis.

Repeat the calculations assuming the system is non-ideal andcompare the results by plotting the ideal and non-ideal cases onthe same graph and comment on the graph.

Q2 Using the equilibrium constant figure for n-heptane, do thefollowing;

1. Plot log K versus log P at 50° F, 150° F, and 250° F (P=20,50, and 600 psia)

2. Plot log K versus log P at the same temperture and pressureassuming ideal solution behaviour.

3. Comment on the plots you obtained
