Using Hess' Law,what Is ΔH°_rxn at 25°C for the Following

Using Hess' law,what is ΔH°_rxn at 25°C for the following reaction? ClF(g) + F₂(g) → ClF₃(g) 2ClF(g) + O₂(g) → Cl2O(g) + OF₂(g) ΔH°_rxn = +167.4kJ/mol
2ClF₃(g) + 2O₂(g) → Cl₂O(g) +3OF₂(g) ΔH°_rxn = +341.4kJ/mol
2F₂(g) + O₂(g) → 2OF₂(g) ΔH°_rxn = -43.4 kJ/mol

A) -217.5 kJ/mol
B) -130.2 kJ/mol
C) 217.5 kJ/mol
D) -108.7 kJ/mol
E) 465.4 kJ/mol
