The Standard Enthalpy of Formation of NH₄Cl(s) Is -315

question 23

Multiple Choice

The standard enthalpy of formation of NH₄Cl(s) is -315.4 kJ/mol. The equation that describes this △H°f is:

• A) NH₄⁺(aq) + Cl^-(aq) → NH₄Cl(s)
• B) 1/2 N₂(g) + 2H₂(g) + 1/2 Cl₂(g) → NH₄Cl(s)
• C) N₂(g) + H₂(g) + Cl₂(g) → 2 NH₄Cl(s)
• D) 1/2 N₂(g) + 1/2 Cl₂(g) + 1/2 H₂(g) → NH₄Cl(s)
• E) N₂(g) + Cl₂(g) + 4 H₂(g) → 2 NH₄Cl(s)
