We have isopropylamine can be described using the one$-$constant Margules model at a temperature

$35C$ :

$G^{\frac{?}{\text{b}\text{a}\text{r}}(Ex)}=A{x}_1{x}_2$

where $A=8525\frac{J}{?}$ mol at this temperalure.

Using this model, determine:

a$)$ If this system will undergo liquid$-$liquid phase separation at this temperature, and if

so$.$ for which range of compositions.

b$)$ The composition of the two liquid plases that will be produced if plase separation is

pussible.

c$)$ For $x_1=0\mathrm{.}32.$ is the single$-$phase mixture stable, unstable, or metastable? If unstable

or metastable. what is the change in Gilbs free energy for phase separation?found that the Gibbs excess of a mixture of methanol and

isopropylamine can be described using the one$-$constant Margules model at a temperature

of $35\backslash$deg C:

$$

$$

$=12$

where A $=8525$ J$/$mol at this temperature.

Using this model, determine:

a$)$ If this system will undergo liquid$-$liquid phase separation at this temperature, and if

so$,$ for which range of compositions.

b$)$ The composition of the two liquid phases that will be produced, if phase separation is

possible.

c$)$ For x$1=0\mathrm{.}32,$ is the single$-$phase mixture stable, unstable, or metastable? If unstable

or metastable, what is the change in Gibbs free energy for phase separation? can someone please solve this step by step. Very urgent. thank you
