S: 1. Draw enthalpy diagrams for each of the reactions in Part A and in Part B. In which reaction does the reactants contain stronger bonds? In which does the products contain stronger bonds? 2. Based on your value of AH for the reaction in part A, a. Predict the value, in kJ/mol, for the AH of the reaction of HNO3(aq) and KOH(aq). b. Predict the value, in kJ/mol, for the AH of the reaction of HSO4(aq) and NaOH(aq). (HINT: Consider the net ionic equation for all three reactions) X 3. The dissolution of NaOH(s) in water has a AH of -44.5 kJ/mol. Based on your value of AH for the reaction in part A, predict the value (kJ/mol) for the AH reaction below: HCl(aq) + NaOH(s) HO(l) + NaCl(aq) = ?? 4. In Part B, instead of extrapolating back to the time of mixing, a student used the temperature taken after 30 seconds as the final temperature. What effect would this have on her calculated AH solution? 24.4 HO 747 25 9
