Question
Use the thermodynamic quantities given below to calculate the theoretical ΔH for this reaction:
NH3 + HCl → NH4Cl
-
ΔH°f for NH3 (aq) = - 80.29 kJ/mol
-
ΔH°f for HCl (aq) = - 167.2 kJ/mol
-
ΔH°f for NH4+ (aq) = - 132.5 kJ/mol
-
ΔH°f for Cl- (aq) = - 167.2 kJ/mol
I found this answer to be -52.21 kJ/mol
