P = P A ° X A+ P B °(1- X Lambda) and P A prime X A = Y A P = Y A [ P A ° X A + P B °(1- X A )] so, (1/ Y A )=1+( P B °/ P A °)((1/ X A )-1) so, x =1+( P B °/ P A °)( y -1) Hence ⇒ (x-1) (PB°/PA°)+1=y so, y=m x+C gives the result

Q. The plots of $\frac{1}{X _{A}}$ (on $y$ -axis) $v s \frac{1}{Y _{A}}$ (on $x$ -axis) (where $X_{A}$ and $Y_{A}$ are the mole fractions of liquid $A$ in liquid and vapour phase respectively) is linear with slope and y-intercept respectively.

$\frac{P _{A}^{0}}{P _{B}^{0}}$ and $\frac{( P _{A}^{0} - P _{B}^{0} )}{P _{B}^{0}}$

$\frac{P _{B}^{0}}{P _{A}^{0}}$ and $\frac{( P _{A}^{0} - P _{B}^{0} )}{P _{B}^{0}}$

$\frac{P _{A}^{0}}{P _{B}^{0}}$ and $\frac{( P _{B}^{0} - P _{A}^{0} )}{P _{B}^{0}}$

$\frac{P _{B}^{0}}{P _{A}^{0}}$ and $\frac{( P _{B}^{0} - P _{A}^{0} )}{P _{B}^{0}}$

Q. The plots of XA​1​ (on y-axis) vsYA​1​ (on x-axis) (where XA​ and YA​ are the mole fractions of liquid A in liquid and vapour phase respectively) is linear with slope and y-intercept respectively.

PB0​PA0​​ and PB0​(PA0​−PB0​)​

PA0​PB0​​ and PB0​(PA0​−PB0​)​

PB0​PA0​​ and PB0​(PB0​−PA0​)​

PA0​PB0​​ and PB0​(PB0​−PA0​)​

P=PA​∘XA​+PB​∘(1−XΛ​) and PA​′XA​=YA​P=YA​[PA​∘XA​+PB​∘(1−XA​)] so, YA​1​=1+PA∘​PB∘​​(XA​1​−1) so, x=1+PA∘​PB∘​​(y−1) Hence ⇒(x−1)PA∘​PB∘​​+1=y so, y=mx+C gives the result

Q. The plots of $\frac{1}{X _{A}}$ (on $y$ -axis) $v s \frac{1}{Y _{A}}$ (on $x$ -axis) (where $X_{A}$ and $Y_{A}$ are the mole fractions of liquid $A$ in liquid and vapour phase respectively) is linear with slope and y-intercept respectively.
