A binary mixture of components $1$ and $2$ form an azeotrope at $66\mathrm{.}8\%($mol$)$ of

component $1.$ It boils at $331\mathrm{.}9$ K at $101\mathrm{.}3$ kPa. At $331\mathrm{.}9$ K$,$ the vapour pressures

are $72\mathrm{.}24$ kPa for component $1$ and $44\mathrm{.}25$ kPa for component $2.$ Determine the

total pressure and vapour composition for a solution containing $50\%($mol$)$

component $1$ boiling at $331\mathrm{.}9$ K
