Question $6(8$ Points$)$

Calculate the bubble temperature $($which falls between $60-100C)$ for a liquid mixture that is $35$

mol$\%$A and $65$mol$\%B.$ The pressure is $\frac{1\mathrm{.}5}{b}ar.$ The liquid mixture is modeled by the $2-$parameter

Margules equation $(A_{12}=1\mathrm{.}25,A_{21}=1\mathrm{.}45),$ and the gas phase is ideal. You have the following

saturation pressure relationships where $P$ is in $($bar$),$ and $T$ is in $(C)$ :

$lo{g}_{10}(P_A^{\text{s}\text{a}\text{t}})=4\mathrm{.}3-\frac{1200}{(T+230)}$

$lo{g}_{10}(P_B^{\text{s}\text{a}\text{t}})=5\mathrm{.}6-\frac{1600}{(T+225)}$
