8.7 Two substances A and B are known to form ideal liquid solutions.A vapour mixture containing 50% (mol) A and 50% (mol) B is at 311 K and 101.3 kPa. This mixture is compressed isothermally until condensation occurs. At what pressure does condensation occur and what is the composition of the liquid that forms? The vapour pressures of A and B are 142 kPa and 122 kPa respectively.
