Problem Details

Use Hess's law to calculate ΔG°rxn using the following information.

CO(g) → C(s) + 1/2 O2(g)         ΔG°rxn = ?

CO2(g) → C(s) + O2(g)              ΔG°rxn = +394.4kJ

CO(g) + 1/2 O2(g) → CO2(g)      ΔG°rxn = -257.2 kJ

A) -60.0 kJ

B) +651.6 kJ

C) -265.8 kJ

D) +137.2 kJ

E) +523.0 kJ
