It has a mixture of acetone vapor and nitrogen. This mixture contains 4.31% vol of acetone and is at a pressure of 1600 mm Hg (absolute) and at a temperature of 25 ° C. The following is requested: 
a. Molar saturation. 
b. Spray temperature for the mixture. 
c. Relative saturation of the mixture. 
d. If the mixture cools down to -5 ° C (the pressure is maintained at 1600 mm Hg) how many moles of acetone condensate per 100 moles of original mixture? log P ° acetone = 7.11714 - 1210.595 / (T + 229.664) T (° C), P ° acetone (Hg mm)

The binary system, acetone(1)-acetonitrile(2) conforms closely to Raoult’s Law. a) Using the vapor-pressure data, prepare a graph showing P vs. x1 and P vs. y1 at 50ºC, and a graph showing T vs. x1 and T vs. y1 at 400 mm Hg. Thus when T is fixed, x1 and y1 vary with P, and when P is fixed, x1 and y1 vary with T. b) The mixture which has an acetone mole fraction of 0.405 is heated slowly (so as...

A vapor mixture of benzene and toluene is slowly cooled inside a constant volume vessel. Initially the pressure inside the vessel is 300 mm Hg and the temperature is 70 C. As the vessel is cooled, the pressure inside the vessel decreases. Assume the vapor behaves like an ideal gas and take the dew point of the mixture to be 60 C. What is the mole fraction of benzene in the initial vapor mixture?

Solids soaked with liquid hexane are dried by being contacted with nitrogen at an elevated temperature. The gas stream leaving the dryer is at 80°C, 1 atm absolute and 50% relative saturation. (a) One of several possibilities for recovering the hexane from the gas is to send the stream to a cooling condenser. The gas stream leaving the condenser would contain 5.00 moles of hexane (out of 100 total moles), and hexane condensate would be recovered at a rate of...
