Given the Reactions Below,compute Δ_rH° for the Reaction

Given the reactions below,compute Δ_rH° for the reaction:
(ΔH's are all given in kJ/mol)
2 MnO₂(s) + CO(g) → Mn₂O₃(s) + CO₂(g)
Reaction Δ_rH°
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

A) -347.3 kJ/mol
B) -46.1 kJ/mol
C) -217.1 kJ/mol
D) -104.5 kJ/mol
E) -389.1 kJ/mol
