Calculate the boiling temperature and the vapor phase mole fraction y1 at 85 kPa of the binary mixture with the liquid phase mole fraction x1 = 0.40. Consider the mixture ideal. The saturation vapor pressures of the components in the mixture are given below and are T (° C);
                              P1sat = exp [14.3 - 2945 / (T + 224)]
                              P2sat = exp [14.2 - 2943 / (T + 209)]

A single-stage liquid/vapor separation for the unknown molecule (1) and molecule (2) mixture with mole fraction z1=0.75 is operated at T=100°C and P=40 kPa. Determine the partial pressure of molecule (1) in the separator. The feeding rate of the mixture is 1mole/s and the molar fraction (V) of the vapor formed is 0.5. Saturated pressure of the molecule (1) is 50.00 kPa and that of the molecule (2) is 20 kPa at the separator temperature. Assume Raoult’s law applies. (8...

A solution that contains nitromethane (1) in acetonitrile (2) is heated at a constant pressure of 1 bar until the first bubble appears. If the temperature of the solution at this point is 85◦C, what is the composition of the original solution? You may assume that the solution is ideal. The saturation pressures for the pure components (in kPa) for T in ◦C are given by ln(p1sat) = 14.2742 – 2945.47/(224 + T) ln(p2sat) = 14.2043 – 2972.64/(209 + T)

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...
