The enthalpy of a binary system of species $1$ and $2$ at fixed $T$ and $P$ is represented by the equation:

$H=400x_1+600x_2+x_1{x}_2(40x_1+20x_2)$

Determine the following:

$($a$)$ Expressions for $\frac{?}{\text{b}\text{a}\text{r}}(H_1)$ and $\frac{?}{\text{b}\text{a}\text{r}}(H_2)$ as a function of $x_1$

$($b$)$ Numerical values for the pure species enthalpies $H_1$ and $H_2$

$($c$)$ Numerical values for the partial enthalpies at infinite dilution
