The vapour pressures of acetone (1) and acetonitrile ( 2 ) can be evaluated by the Antoine equations lnP1sat=14.5463T35.932940.46lnP2sat=14.2724T49.152945.47 where T is in K and P in KPa. Assume that the solutions formed by these are ideal. a) At 90kPa and x1=0.45, the equilibrium temperature T= and vapour composition y1= b) At 90kPa and y1=0.45, the equilibrium temperature T. and liquid composition x1= c) The fraction v of the system that is vapour at 327K and 70KPa when the overall composition of the system is 85 mole per cent acetone.
