SOLVE THE PROBLEM $11\mathrm{.}10$ ONLY. $11\mathrm{.}9$ IS ADDITONAL INFORMATION

$11\mathrm{.}9.$ Infinite dilution activity coefficients are known for a binary mixture of acetonitrile

$(C_2{H}_3(N))(1)$ and water $(H_{2}O)(2)$ at $25C$ :

$ln{}_1^{}=8\mathrm{.}22,ln{}_2^{}=14\mathrm{.}39$

In addition, the ratio of molar liquid volumes, $\frac{V_1}{V_2}=2\mathrm{.}89.$ Using the two$-$suffix

Margules, van Laar, Wilson, and NRTL $($with ${}_{12}=0\mathrm{.}535)$ models, tabulate and plot

In ${}_i(i=1,2)$ from $x_1=0$ to $1\mathrm{.}0.$

$11\mathrm{.}10.$ Given the data of Problem $11\mathrm{.}9,$ determine UNIQUAC binary interaction parameters

${}_{12}$ and ${}_{21}$ with $z=10$ if values for $r_i,q_i,$ and $q_i$ are given below. Tabulate and plot
