Using Henry's Law, solve the following problem: The vapour pressure of a pure liquid A is 23 kPa at 20 ºC and the Henry’s law constant of B in liquid A is 73 kPa. Calculate the vapour pressure of each component, the total pressure, and the composition of the vapour phase when the mole fraction of B is 0.066 on the assumption that the conditions of the ideal - dilute solution are satisfied at this concentration

P3.7. A gaseous mixture is made of two gases. The saturated vapour pressures over the pure liquids are p = 30 kPa and p = 40 kPa at temperature T = 320K. The mole fraction of the first component is equal to xe = 0.6. The mixture was isothermally compressed up to the moment when the first drop of liquid appeared. Find the particular pressure when this phenomenon occurred. The mixture may be treated as an ideal one.

Exercise 6. Estimate the K-values and a of a vapour-liquid mixture of water (W) and methane (M) at P = 2 atm, T = 20 and 80°C. What is the effect of T on the component distribution? At these conditions, water exists mainly in the liquid phase and will follow Raoult's law. Because methane has a critical temperature of -82.5 °C, well below the temperatures of interest, it will exist mainly in the and follow Henry's law. Table 1: From...
