Assuming Raoult's law to be valid, prepare i$)$ a $T-x-y$ diagram and ii$)$ an $x-y$ diagram for a pressure of

$70$kPa for the binary system Benzene$/$Toluene$.$

Include a description of the steps you followed to get them to get the full mark.

$ln{P}^{\text{s}\text{a}\text{t}}=A-\frac{B}{T+C}$

$P^{\text{s}\text{a}\text{t}}=$ Vapour pressure KPa

$T=$ Temperature in $K$
