Two components A and B form an ideal solution. The mole fraction of A and B in ideal solutions are \[{{X}_{A}}\] and  \[{{X}_{B}},\] while that of in vapour phase, these components have their mole fractions as \[{{Y}_{A}}\] and \[{{Y}_{B}}\] then, the slope and intercept of plot of \[\frac{1}{{{Y}_{A}}}\] us \[\frac{1}{{{X}_{A}}}\] will be

A. \[\frac{p_{B}^{0}}{p_{A}^{0}},\frac{p_{A}^{0}-p_{B}^{0}}{p_{A}^{0}}\]
B. \[\frac{p_{B}^{0}}{p_{A}^{0}},\frac{p_{A}^{0}+p_{B}^{0}}{p_{A}^{0}}\]
C. \[\frac{p_{A}^{0}}{p_{B}^{0}},\frac{p_{A}^{0}+p_{B}^{0}}{p_{A}^{0}}\]
D. \[\frac{p_{A}^{0}}{p_{B}^{0}},\frac{p_{A}^{0}}{p_{A}^{0}-p_{B}^{0}}\]
Answer» B. \[\frac{p_{B}^{0}}{p_{A}^{0}},\frac{p_{A}^{0}+p_{B}^{0}}{p_{A}^{0}}\]
