Question

Part A What is the significance of the horizontal line between points X and Y? a) A boiling liquid with composition X will produce vapor with composition Y. b) The point X gives the vapor composition of the less volatile component and Y gives the vapor composition of the more volatile component. The line gives the difference. c)The length of the line XY corresponds to the difference in boiling point of components A and B. d)A boiling liquid with composition Y will produce a vapor with composition X. Part B Using the phase diagram, determine the molar composition of the vapor in equilibrium with a boiling liquid that has a composition of 80.% A and 20.% B. Percentage vapor composition A = % Percentage vapor composition B = % What is the boiling point of this liquid? Boiling point = 9 Shown below is the phase diagram for a typical liquid mixture of two components, A and B. Vapor 150 130--__- 110- A , 70- 50- Liquid A 100%-80%-60%-?40% 20%-?096 090-2096 ._. 40%-60%-80%-100% ?

The horizontal line joining X and Y is called tie line, and it indicates the equilibrium composition of more volatile compound in liquid and vapour. Option (A) is correct : A boiling liquid with composition X will produce the vapour of composiition Y. PART B : Draw a vertical line from the point on X axis at (80% A and 20% B point) to the lower bubble point curve. Then from this point on the bubble curve, draw a horizontal line to the upper dew point curve. The point on the dew point curve indicates 90% A and 10% B and 100 degree Celsius temperature.( Boiling point)
