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