Question #1300203

Calculating ΔH°rxn problem! - Chemistry?

Oxidation of gaseous ClF by F2 yields liquid ClF3, an important fluorinating agent. Use the following thermochemical equations to calculate ΔH°rxn for the production of ClF3. (1) 2 ClF(g) + O2(g) → Cl2O(g) + OF2(g) ΔH° = 167.5 kJ (2) 2 F2(g) + O2(g) → 2 OF2(g) ΔH° = -43.5 kJ (3) 2 ClF3(l) + 2 O2(g) → Cl2O(g) + 3 OF2(g) ΔH° = 394.1 kJ
