Question
Consider the following two temperature vs composition phase diagrams of two ideal binary
mixtures – one consisting of liquids A and Band the other consisting of liquids Cand D- with
TAi TB, Tc, and Tp being the boiling point temperatures of A, B, C, and D respectively at constant
pressure. The curves in red are the vaporization curves while the curves in blue are the
condensation curves. PA, PB, Pc, and Pp* are the vapour pressures of A, B, C, and D respectively.
Tg - TA is greater than Tp* - Te. The number of vaporization-condensation cycles required to
achieve greater than 99 % purity in the first solution is NAB and the number of vaporization-
condensation cycles required to achieve greater than 99 % purity in the second solution is NcD
Which of the following statements is true?
