1.	An ideal solution ois formed by mixing two volatile liquids A and B. X_(A) and X_(B) are the molefractions of A and B respectively in the solution and Y_(A) and Y_(B) are the molre fractions of A and B respectively in the vapour phase. A plot of 1//Y_(A) along y-axis against 1//X_(A) along x-axis gives a straight line. What is the slope of the straight line? (where p_(A)^(@) and p_(B)^(@) are the vapour pressures of the pure components A and B respectively)
Answer» `p_(B)^(@)//p_(A)^(@)` `p_(A)^(@)//p_(B)^(@)` `p_(B)^(@)-p_(A)^(@)` `p_(A)^(@)-p_(B)^(@)` SOLUTION :From point 2, PAGE 2/28, `(1)/(y_(A))=(p_(B)^(@))/(p_(A)^(@))=(1)/(x_(A))+(p_(A)^(@)-p_(B)^(@))/(p_(A)^(@))""(y=mx+c)` Hence, plot of `1//y_(A)` along y-axis versus `1//x_(A)`along x-axis will be straight LINE with slope `=p_(B)^(@)//p_(A)^(@)`.
