A compare the results of question c with the experimental

Question

A. Compare the results of question "C" with the experimental results of the reaction:

NH₃ + HCl à NH₄Cl (calculate the percent difference).

B. Use the thermodynamic quantities given below to calculate the theoretical ΔH for this reaction: NH₃ + HCl à NH₄Cl

• ΔH°ffor NH₃(aq) = - 80.29 kJ/mol
• ΔH°ffor HCl (aq) = - 167.2 kJ/mol
• ΔH°ffor NH₄⁺(aq) = - 132.5 kJ/mol
• ΔH°ffor Cl^-(aq) = - 167.2 kJ/mol
