Q$1$:$-$

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

$P_1$ set $=14\mathrm{.}5463-2940.\frac{46}{t+237\mathrm{.}22}$

$in{P}_2$ set $=14\mathrm{.}2724-2940.\frac{47}{t+224\mathrm{.}00}$

$in{P}_3$ set $=14\mathrm{.}2043-2972.\frac{64}{t+209\mathrm{.}00}$

where $t$ is in $e$ and vepor pressures ere in

H$.$Pe$.$ Assuming that Racults ew is eccropate this system, celculete:

$A$ : $P$ and $\{yK\}$ given that $t=80c{x}_1=0\mathrm{.}25$

$x_2=0,35x_3=0,40$

$B$ : t and $\{xK\}$ given that $P=90KPQ{y}_1=0,60y_2=0,2$ and $y_3=0,2$
