atm, where x is the mole fraction in the liquid and y the mole
fraction in the vapour at equilibrium.
e/°C 110.9 112.0 114.0 115.8 117.3 119.0 121.1 123.0
xM
0.908 0.795 0.615 0.527 0.408 0.300 0.203 0.097
yM
0.923 0.836 0.698 0.624 0.527 0.410 0.297 0.164
The bọiling points are 110.6°C and 125.6°C, for M and O
respectively."
A. Plot the temperature-composition diagram for the
mixture.
B. What is the composition of the vapour in equilibrium with
the liquid of composition (a) xM = 0.750 and (b) xo =
0.750? [0.82, 0.36]
