Question

Which of the following shows behavior of binary liquid solution?

• A. Plot of $1/{\rho }_{total}$ vs $1/Y_A$, mole fraction of $A$ in vapour phase
• B. Plot of $1/{\rho }_{total}$ vs $1/Y_B$ is linear
  
• C. Plot of $1/{\rho }_{total}$ vs $1/\left(Y_B{Y}_A\right)$ is linear
  
• D. Plot of $1/{\rho }_{total}$ vs $Y_A$ is linear
  

Answer 1

The correct option is D Plot of $1/{\rho }_{total}$ vs $Y_A$ is linear

For binary liquid solution, plot of $\frac{1}{P_{total}}$ vs $Y_B$ is linear.
$\frac{P_B}{P_{total}}=Y_B$

$\frac{1}{P_{total}}\propto Y_B$
