These lines (I and II) pass through the points for which

x_{1}

and

x_{2}

are equal to unity. The plot (line III) of

p_{total}

versus

x_{2}

is linear.

The plot of vapour pressure and mole fraction of an ideal solution at constant temperature i.e. the dashed lines I and II represent the partial pressure of the components. The total vapour pressure is given by line marked III.

Q. The diagram given below represents the vapour pressure and mole fraction of an ideal solution of component $1$ and $2$ . Answer the following questions.
What does lines I, II and III indicate?

$I - p_{1} II - p_{total} III - p_{2}$

$I - p_{2} II - p_{1} III - p_{total}$

$I - p_{1} II - p_{2} III - p_{total}$

$I - p_{1} II - p_{total} III - p_{1}$
