Which of the following behaviour is true about the ideal binary liquid solution?

Options

A. Plot of `P_("Total") vs X_(A)` is non-linear
B. Plot of `P_("Total") vs X_(B)` is linear
C. Plot of `P_("Total")vs X_(B)` is linear with slope `= 0`
D. Plot of `P_("Total") vs X_(A)` is linear with slope `= 0`

Answer

B

Explanation

For a ideal binary solution
`P_("Total") = p_(A)^(@) X_(A) +p_(B)^(@) X_(B)`
`:.` plot of `P_("Total")` is `X_(A)` or `P_("Total")` vs `X_(B)` is a straight line
