An ideal benzene toluene mixture contains 6 moles of benzene and 4 moles of toluene at 25 ° C. The saturation steam pressure of pure benzene at 25 ° C is 96 Torr, the saturation steam pressure of pure toluene is 29 Torr. Initially, the mixture at 760 Torr pressure is only liquid. The total pressure is then slowly reduced to a pressure of 60 Torr. Calculate the composition of liquid phase and vapor phase, and liquid and vapor mole fractions. (please show all the steps)

An ideal benzene toluene mixture contains 6 moles of benzene and
4 moles of toluene at 25 ° C. The saturated vapor pressure of pure
benzene at 25 ° C is 96 Torr, the saturated vapor pressure of pure
toluene is 29 Torr. Initially, the mixture at 760 Torr pressure is
only liquid. The total pressure is then slowly reduced to a
pressure of 60 Torr. Calculate the composition of liquid phase and
vapor phase, and calculate liquid and vapor...

A mixture of 4.00 gram-moles of benzene and 6.00 gram-moles of
toluene are placed in a closed cylinder equipped with a piston. The
cylinder is immersed in a bath of boiling water that maintains the
temperature at 100.0°C. The force exerted on the piston can be
varied to adjust the cylinder pressure to any desired values. The
pressure is initially 1300 mm Hg and is gradually lowered to 600 mm
Hg. Use the Pxy diagram below to convince yourself that...

A vessel contains a mixture of equimolar liquid benzene and
liquid toluene that is in equilibrium with their vapors and air.
The temperature of the mixture is 40 degrees celsius. The mole
fraction of air in the vapor phase is .6 or 60%. What is the total
pressure and the mole fraction of benzene in the vapor phase?

A liquid is a mixture of benzene (C6H6) and toluene (C7H8). The
sample contains 20.309 grams of benzene and 114.254 grams of
toluene. At a given temperature, pure benzene has a vapor pressure
of 38.50 torr, while pure toluene has a vapor pressure of 8.99
torr. What is the total combined vapor pressure of the two liquids
(in torr)?

A binary mixture of benzene and toluene will be separated by
continuous distillation. The mixture consists of 20% mol of benzene
and 80% mol of toluene at the bubble point of 91ºC. The binary
mixture is available at 100 mol h-1 and the separation should
deliver a distillate product that has a concentration of 90% mol of
benzene and that contains half of the benzene in the feed stream.
a) Plot the equilibrium line for benzene. b) Determine the minimum...

benzene and 2.0 mol toluene. Some of the solution evaporates in a
closed system. What is the mole fraction of benzene in the
vapor?
A. 0.33

A mixture of benzene and toluene is in a tank whose pressure is
maintained at 2.0 atm. Observation through a sight glass on the
vessel shows that half of the tank volume is occupied by liquid.
Analysis shows that the liquid contains 50.0 wt% benzene and the
balance toluene. Raoult's law applies at all composition s, and the
density of the liquid is essentially independent of temperature.
Estimate (a) the temperature and (b) the fraction of the system
mass in...

A benzene/toluene liquid mixture consisting of 31 mole% benzene
is fed to a reboiler, where 1250 KW of heat is provided causing the
mixture to partially vaporize. The vapor output has a flowrate of
80 kmol/hr and consists of 40 mole% benzene. The liquid output has
a flowrate of 100 kmol/hr. The two output streams are in
equilibrium and exit the reboiler at 130 oC. Determine the
temperature of the feed stream. Neglect the effect of pressure and
consider the...

For a liquid mixture of benzene and toluene of equal composition
by mass, perform the following:
a) Using Raoult’s law , calculate the total pressure and mole
fractions of each substance in a gas phase containing only benzene
and toluene vapor in equilibrium with the given liquid mixture at
60oC.
b) Prove that the bubble point of the liquid mixture at
pressure, P = 0.715 atm is 80OC

A mixture of benzene and toluene is in equilibrium with its
vapor at 50oC. What mole fraction of benzene is in the vapor phase?
You may assume that this system follows Raoult's Law. Note: when
solving Antoine's equation it is best to keep all sig figs through
calculation and then truncate them at the end.
