Answer to Question #196103 in General Chemistry for Riane Rae

Question #196103

CCl 4 , an important commercial solvent, is prepared by the reaction of Cl 2 (g) with a carbon

compound. Determine ΔH o for the reaction:

CS 2 (l) + 3 Cl 2 (g) → CCl 4 (l) + S 2 Cl 2 (l)

Use appropriate data from the following listing.

CS 2 (l) + 3O 2 (g) → CO 2 (g) + 2SO 2 (g) ΔH o = -1077 kJ

2 S (s) + Cl 2 (g) → S 2 Cl 2 (l) ΔH o = -58.2 kJ

C (s) + 2 Cl 2 (g) → CCl 4 (l) ΔH o = -135.4 kJ

S (s) + O 2 (g) → SO 2 (g) ΔH o = -296.8 kJ

SO 2 (g) + Cl 2 (g) → SO 2 Cl 2 (l) ΔH o = +97.3 kJ

C (s) + O 2 (g) → CO 2 (g) ΔH o = -393.5 kJ

CCl 4 (l) + O 2 (g) → COCl 2 (g) + Cl 2 O (g) ΔH o = -5.2 kJ
