At 25°C, the following heats of reaction are known: 

2ClF(g) + O₂(g) → Cl₂O(g) + F₂O(g ΔH°_rxn = 167.4 kJ/mol

2ClF₃(g) + 2O₂(g) → Cl₂O(g) + 3F₂O(g) ΔH°_rxn = 341.4 kJ/mol

2F₂(g) + O₂(g) → 2F2O(g) ΔH°_rxn = –43.4 kJ/mol

At the same temperature, use Hess’s law to calculate ΔH°_rxn for the reaction:

ClF(g) + F₂(g) → ClF₃(g)

(A) –217.5 kJ/mol

(B) –130.2 kJ/mol

(C) 217.5 kJ/mol

(D) –108.7 kJ/mol
