Thermodynamic Quantities for Selected Substances at 298.15K (25 °C) Substanoe AHf(kJ/mol) Gf(kJ/mol) S(J/K-mol) Caldium 41.4 104.6 200.8 -748.1 CaCl2 (s) Ca2+ (a) -795.8 226.7 209.2 Chlorine C12 (8) Cl- (aq) 222.96 -167.2 -131.2 56.5 Oxygen O2 (8) H20 (1) 205.0 69.91 -285.83 237.13 Phosphorus P2 (8) PC13 (8) POCI3 () -5422 144.3 -288.1 103.7 -269.6 -502.5 218.1 311.7 325 Sulfur S (s, rhombic) So28) S03(g) -269.9 -395.2 -300.4 -370.4 31.88 248.5 256.2

Explanation / Answer

dG = Gproducts - Greactants

dG = SO2 - (S + O2)

dG = -300.4 - (0 + 0)

dG = -300.4 kJ/mol
