P3.7. A gaseous mixture is made of two gases. The saturated vapour pressures over the pure...
The vapour pressures of the pure components P and Q are 700 Torr and 500 Torr respectively. When the two phases are in equilibrium at 1.0 atm, the mole fraction of P in the liquid phase is 0.6 and in the vapour phase 0.4. The activity co-efficient of compound P in the solution on the basis of Raoult’s law is (a) 0.60 (b) 0.72 (c) 0.92 (d) 1.01
3. Consider the hexafluorobenzene(1)-cyclohexane(2) mixture at 50 °C. The vapor pressures for the pure species are psat = 34.10 kPa and Pat = 36.30 kPa. a. (10%) Assuming Raoult's law, calculate the pressure range of the 2-phase region when the mole fraction of hexaflourobenzene is 0.8. b. (10%) Experiments show that this mixture at 50°C has an azeotrope. Show mathematically that Raoult's law is unable to predict an azeotropic behavior. c. (10%) Use the modified Raoult's law with the van...

Dalton's law states that the total pressure. Patel of a mixture of gases in a container equals the sum of the pressures of each individual gas: Part A P la P +1 +P: +.. The partial pressure of the first component. P. is equal to the mole fraction of this component, XI. times the total pressure of the mixture: P1= X X X Three gases (8.00 g of methane, CH,. 18.0 y of ethane, C,Hand an unknown amount of propane,...
