Given below are values of G^E /J·mol⁻¹, H^E /J·mol⁻¹, and C^E_P / J · mol ⁻¹· K⁻¹ for some equimolar binary liquid mixtures at 298.15 K. Estimate values of G^E, H^E, and S^E at 328.15 K for one of the equimolar mixtures by two procedures: (I) Use all the data; (II) Assume C^E_P = 0. Compare and discuss your results for the two procedures.

(a) Acetone/chloroform: G^E = − 622, H^E = − 1920, C^E_P = 4.2.

(b) Acetone/n-hexane: G^E = 1095, H^E = 1595, C^E_P = 3.3.

(c) Benzene/isooctane: G^E = 407, H^E = 984, C^E_P = − 2.7.

(d) Chloroform/ethanol: G^E = 632, H^E = − 208, C^E_P = 23.0.

(e) Ethanol/n-heptane: G^E = 1445, H^E = 605, C^E_P = 11.0.

(f) Ethanol/water: G^E = 734, H^E = − 416, C^E_P = 11.0.

(g) Ethyl acetate/n-heptane: G^E = 759, H^E = 1465, C^E_P = − 8.0.
