Chapter 10, Problem 10.14P

For a particular binary liquid solution at constant T and P, the molar enthalpies of mixtures are represented by the equation

$H=x_1\left(a_1+b_1{x}_1\right)+x_2\left(a_2+b_2{x}_2\right)$

where the $a_i$ , and $b_i$ , are constants. Because the equation has the form of Eq. (10.11), it might be that ${\bar{H}}_i=a_i+b_i{x}_i$ . Show whether this is true.
