For Antoine equation in the form

log10(VP) = A- B/(T+C)

with VP in mm Hg and T degree C, the constants for n-pentane are: A=6.853, B=1064.8, C=233.01. n-hexane constants are: A=6.876, B=1171.17, C=224.41.

a. Predict the vapor pressure at 0 degrees C for pure n-pentane.

b. Predict the boiling point of pure n-pentane at 3 atm pressure.

c. Predict the boiling pressure if pure n-pentane is boiling at 0 degrres C.

d. At a pressure of 500 mm Hg and temperature of 30 degrees C, predict the K values for n-pentane and n-hexane using Raoult's law.

e. For a binary mixture with two phases at equilibrium , F= C-P+2= 2-2+2= 2 degrees of freedom. If T= 30 degrees C and p= 500 mm Hg, determine the mole fractions in the liquid and vapor phases of an equilibrium mixture of n-pentane and n-hexane.

f. One mole of mixture that is 75 mol% n-pentane and 25 mol% n-hexane is placed in a closed chamber. The pressure is adjusted to 500 mm Hg and the temperature to 30 degrees C. The vapor and liquid mole fractions were found in part e. How many moles of liquid and how many moles of vapor are there at equilibrium?

g. If 1 mole/min of a mixture is 75 mol% n-pentane and 25 mol% n-hexane is fed continouosly to equilibrium flash chamber operating at 30 degrees C and 500 mm Hg, what are the flow rates of the liquid and vapor products?
