8 Enthalpy Change for the Decomposition of Ammonium Chloride Essay8_Dissociation of Ammonium Chloride Steps EXPERIMENT 3: Write out the reaction, NH4Cl(s) NH3(g) + HCl(g) as a series of steps which include the reactions observed in Experiments 2 and 3. Then calculate the overall reaction enthalpy. Use the known enthalpies for the change of state of NH3 and HCI given below. NH3(g) → NH3(aq) HCI(g) → HCl(aq) - NH4CI(S)→ NH4Cl(aq) HCl(aq) + NH3(aq) → NH4Cl(aq)) NH3(g) → NH3(aq)) - HCI(g) → HCl(aq)) AH=-34.64 kJ/mol AH = -75.14 kJ/mol AH₁ = 14.7 kJ/mol AH₂= -33 kJ/mol AH3-34.64 kJ/mol AH4-75.14 kJ/mol
