Problem Set 5 - Chapter 5 3. Calculate ΔH for the reaction 4 NO (g) + 6 H₂O (g) → 4 NH₃ (g) + 5 O₂ (g), from the following data. - N₂ (g) + O₂ (g) → 2 NO (g) ΔH = -180.5 kJ - N₂ (g) + 3 H₂ (g) → 2 NH₃ (g) ΔH = -91.8 kJ - 2 H₂ (g) + O₂ (g) → 2 H₂O (g) ΔH = -483.6 kJ 4. Calculate ΔH for the reaction 2 Al (s) + 3 Cl₂ (g) → 2 AlCl₃ (s), given: - 2 Al (s) + 6 HCl (aq) → 2 AlCl₃ (aq) + 3 H₂ (g) ΔH = -1049 kJ - HCl (g) → HCl (aq) ΔH = -74.8 kJ - H₂ (g) + Cl₂ (g) → 2 HCl (g) ΔH = -184.5 kJ - AlCl₃ (s) → AlCl₃ (aq) ΔH = -323 kJ (Note: The text provided above is a transcription intended for educational purposes and assumes familiarity with chemical reactions and thermodynamics concepts.)
