Which one of the following reactions would produce the largest amount of heat per mole of hydrogen? A) C (s) + 2 H₂ (g) → CH4 (g) ΔH° = -74.9 kJ/mol B) N₂O (g) + 3 H₂ (g) → N₂H4 (g) + H₂O (I) ΔH° = -316.8 kJ/mol C) 2 H₂ (g) + O₂ (g) → 2 H₂O (I) ΔH° = -571.6 kJ/mol D) N₂ (g) + 3 H₂ (g) → 2 NH3 (g) ΔH° = -91.8 kJ/mol
