$11\mathrm{.}9.$ 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

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