Using modified Raoult's law, obtain the $P-x_1-y_1$ phase diagram and compare with the

experimental values in the table. For the ${}_i$ activity coefficients, use the Wilson equations,

$(13\mathrm{.}46)$ and $(13\mathrm{.}47).$ See equation $(13\mathrm{.}53)$ for the T$-$dependence of the ${}_{12}$ and ${}_{21}$ parameters.

The molar volumes of $2-$propanol and benzene are $76\mathrm{.}4c\frac{m^3}{m}ol$ and $89\mathrm{.}41c\frac{m^3}{m}ol$

respectively. Attach your calculations including equations used.
