The plots of (1)/(X_(A))vs.(1)/(Y_(A)) (where X_(A) and Y_(A) are the mole fraction of liquid A in liquid and vapour phase respectively) is linear with slope and intercept respctively are given as: |

Answer» `P_(A)^(@)/P_(B)^(@),((P_(A)^(@)-P_(B)^(@)))/(P_(B)^(@))` `P_(A)=X_(A)P_(A)^(@),P_(B)=X_(B)P_(S)^(@)` `Y_(A)P_(A)/(P_(A)+P_(B))=(x_(B)P_(S)^(@))/(X_(A)P_(A)^(@)+X_(B)P_(B)^(@))` `or 1/Y_(A)=(P_(A)^(@)-P_(B)^(@))/P_(A)^(@)+P_(B)^(@)/P_(A)^(@)xx1/X_(A)` `or P_(B)^(@)/(X_(A)P_(A)^(@))=1/Y_(A)-[(P_(A)^(@)-P_(B)^(@)]/P_(A)]` `1/X_(A)=P_(A)^(@)/P_(B)^(@)[1/Y_(A)+((P_(B)^(@)-P_(B)^(@)))/P_(A)^(@)]` `=P_(A)^(@)/P_(B)^(@)xx1/Y_(A)+((P_(B)^(@)-P_(A)^(@)))/P_(B)^(@)` Hence PLOT of `1/X_(A)vs1/Y_(A)` will be liner with slope =`P_(A)^(@)/P_(B)^(@)"and intercept"=((P_(B)^(@)-P_(A)^(@)))/P_(B)^(@)` |
