Question

Attached is a temperature-composition data with temperature in oC on the vertical axis and x = mole fraction liquid and y = mole                    fraction vapor on the horizontal axis. At a temperature of 114 oC what is the composition of the liquid according to this data?      

C        110.9     112         114     115.8     117.3        119      121.1      123

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

Explanation / Answer

Xm=0.615 Ym= 0.698
