# Question

Given the following data:

2ClF(g) + O2(g) → Cl2O(g) + F2O(g) ΔH = 167.4 kJ

2ClF3(g) + 2O2(g) → Cl2O(g) + 3F2O(g) ΔH = 341.4 kJ

2F2(g) + O2(g) → 2F2O(g) ΔH = –43.4 kJ

Calculate ΔH for the reaction ClF(g) + F2(g) → ClF3(g)

2ClF(g) + O2(g) → Cl2O(g) + F2O(g) ΔH = 167.4 kJ

2ClF3(g) + 2O2(g) → Cl2O(g) + 3F2O(g) ΔH = 341.4 kJ

2F2(g) + O2(g) → 2F2O(g) ΔH = –43.4 kJ

Calculate ΔH for the reaction ClF(g) + F2(g) → ClF3(g)
