OUESTION $2$

For the symmetrical Margules equation,

$\frac{g^E}{RT}=A{x}_1{x}_2$

Plot the LLE curve for the case where $A$ is a function of temperature as follows:

$A=\frac{-975}{T}+22\mathrm{.}4-3lnT$

Note that for symmetrical LLE curves,

$x_1^{}=1-x_1^{}$

As a starting point, use the equilibrium relationship in the form:

$ln{}_1^{}-ln{}_1^{}=ln(\frac{x_1^{}}{x_1^{}})$
