Since it is the process of condensation(i.e. is the process in which vapour turn to liquid while coming contact with some comparatively cold body) . In graph there are two temperature 110° C and 80° C where liquid and vapour collides but cold temperature is 80°C and at that temperature our benzene mole fraction is 1.00 mole. This is our answer.

Problem 4.40 Sequential Distillation A liquid mixture containing 30.0 mole% benzene (B), 25.0% toluene (T), and the balance xylene (X) is fed to a distillation column. The bottoms product contains 98.0 mole% X and no B, and 85.5% of the X in the feed is recovered in this stream. The overhead product is fed to a second column. The overhead product from the second column contains 91.0% of the B in the feed to this column. The composition of this...
