Using enthalpies of formation, calculate ΔΗ° for the following reaction at 25°C. Also calculate AS for this reaction from standard entropies at 25°C. Use these values to calculate AGO for the reaction at this temperature. Species AH (kJ/mol) S (J/mol.K) COC12 (9) H₂O(1) CO₂(g) HCl(g) ΔΗ° = AS° AGⓇ -220.1 -285.8 -393.5 -92.31 KJ J/K 283.9 kJ 69.95 COC12(g) + H₂O(1) → CO₂ (g) + 2HCl(g) 213.7 186.8
