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 points)
