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)?
Explain your answer
