Question:

Following are the slightly smoothed heat-of-mixing data of R. P. Rastogi, J. Nath, and J. Misra [J. Chem. Thermodyn., 3, 307 (1971)] for the system trichloromethane (component 1) and 1,2,4-trimethyl benzene at 35°C.

*1 0.2108 0.2834 0.3023 0.4285 0.4498 0.5504 mixH (kJ/mol) -738 -900 -933 -1083 - 1097 -1095 mixH 21 0.5562

a. From the information in this table, calculate the quantity (Δ_mixH)/(x₁x₂) at each of the reported compositions.

b. Compute the difference between each of the partial molar and pure-component molar enthalpies for this system at each composition.
