(b) What is the composition of the first bubble formed. (c) If the pressure is reduced further, at what pressure does the last trace of liquid disapper? (d) What is the composition of the last drop of liquid? (e) What will be the pressure, composition of the liquid and the composition of vapour. when 1 mol of the mixture has been vaporized? Given P_(T)^(0)=100mmHg
Answer» Answer :(a) `70mmHg` (B) `Y_(A)=2//7,Y_(B)=5//7` (c) `P=400//7=57.14mm` (d) `X_(A)=(5)/(7),X_(B)=(2)/(7)` (E) `63.25 MM` (liquid composition `0.3875,06125`) (VAPOUR composition `0.6125,0.3875`)
