Given the reactions below, compute ΔrH° for the reaction:
(ΔH's are all given in kJ/mol)

2 MnO2(s) + CO(g) → Mn2O3(s) + CO2(g)

ReactionΔrH°
MnO2(s) + CO(g)  → MnO(s) + CO2(g)  -150.6
Mn3O4(s) + CO(g)  → 3 MnO(s) + CO2(g) -54.4
3 Mn2O3(s) + CO(g)  → 2 Mn3O4(s) + CO2(g)  -142.3

▸ -347.3 kJ/mol

▸ -46.1 kJ/mol

▸ -217.1 kJ/mol

▸ -104.5 kJ/mol

▸ -389.1 kJ/mol
