Q$1$:$-$

For the acetone $(1)/$acetonitrile $(2)/$ nitromethen $(3)$ system, we have the follow ing the following

$P_1$ set $=14\mathrm{.}5463-2\mathrm{.}940.\frac{46}{t+237\mathrm{.}22}$

$in{P}_2$ Set $=14\mathrm{.}2724-2\mathrm{.}940.\frac{47}{t+224\mathrm{.}00}$

$in{P}_3$ set $=14\mathrm{.}2043-2\mathrm{.}972.\frac{64}{t+209\mathrm{.}00}$

where $t$ is in $e$ und vepor pressures ere in H$.$ Pe$,$ Assuming that Racults ew is eccrapate this system, celculete: $A$:$P$ end $\{yK\}$ given that ts $80c{x}_1=0\mathrm{.}25$

$x_{25}=0,35,x_3=0,40$

$B$:$+-$ end $\{xK{\}}_3$ given that $P_{5}90KPR{y}_1=0,60,y_{25},2$ and $y_3=0,2$
