`X_(A)` and `X_(B)` are the mole fraction of A and B respectively in liquid phase `y_(A)` and `y_(B)` are the mole fraction of A and B respective in vapour phase. Find out the slope of straight line if a graph is plotted `(1)/(y_(A))` along Y-axis against `(1)/(x_(A))` along X-axis gives straight line `[p_(A)^(@)` and `p_(B)^(@)` are vapour pressure of pure components A and B].

Options

A. `P_(B)^(@)/P_(A)^(@)`
B. `P_(A)^(@)/P_(B)^(@)`
C. `P_(B)^(@)-P_(A)^(@)`
D. `P_(A)^(@)-P_(B)^(@)`

Answer

a
