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.
