a. Determine the bubble-point temperature of an equimolar liquid mixture of n-hexane and a-heptane of

I atm pressure. Also, determine the composition of the bubble of vapor that forms. (Note: for this

calculation, you know the composition of the liquid phase; the temperature must be such that, wing

Raoult's law, the sum of partial pressures of the two components = 1 atm.)

b. Suppose the liquid mixture composition were & boom - 0.4, & bepay -0.6. Without any calculations,

would the bubble-point temperature at I atm pressure be higher or lower than the value found in (a)?

Explain your answer.

c. Determine the bubble-point temperature of an equimolar liquid mixbare of n-hexane and n-hoptant at

1 5 atm pressure. Also, determine the composition of the bubble of vapor that forms. (Note: for this

calculation, you know the composition of the liquid phase; the temperature must be such that, wing

Raoul's law, the sum of partial pressures of the two components = 15 mm)

d. Determine the dew-point temperature of an equimolar vapor mixture of n-hexane and n-heptane at 1

atm pressure. Also, determine the composition of the drop of liquid that forms. (Note: for this

calculation, you know the partial pressures in the vapor phase; the temperature must be such that, using

Raoult's law, the sum of the resulting mole fractions in the liquid phase = 1.)

e. Suppose the vapor mixture composition Wife Skin -04, super -0.6. Without any calculations.

would the dew-point temperature at I aim pressure be higher or lower than the value found in (d)?
