Problem

Use Hess's law to calculate ΔG°rxn using the following information.
H2O(g) + C(s) → CO(g) + H2(g)          ΔG°rxn = ?
H2(g) + ½ O2(g)→ H2O(g)                 ΔG°rxn = -228.6 kJ
C(s)+ ½ O2(g) → CO(g)                     ΔG°rxn = -137.2 kJ

A) -365.8 kJ
B) +365.8 kJ
C) -91.4 kJ
D) +91.4 kJ
E) more information is required
