Do 10.12 only please

The enthalpy of a binary liquid system of species 1 and 2 at fixed T and P is represented by the equation: H=400x1+600x2+x1x2(40x1+20x2) where H is in Jmol1. Determine expressions for H1 and H2 as functions of x1, numerical values for the pure-species enthalpies H1 and H2, and numerical values for the partial enthalpies at infinite dilution H1 and H2. (c) Show that Eqs. (B) and [ (C) satisfy Eq. (10.14), the Gibbs/Duhem equation. (d) Show that at constant T and P, (dH1/dx1)x1=1=(dH2/dx1)x1=0=0 show their values
