An ideal solution is formed by mixing two volatile liquids A and B. XA and XB are the mole fractions of A and B respectively in the solution and Yo and Y, are the mole fractions of A and B respectively in the vapour phase. A plot of 1YAalong y-axis against, along x-axis gives a 1XAstraight line. What is the slope of the straight line ?
