Seven reactions are shown below. Using the table of standard bond energies, enter a heat of reaction for each of these in the designated answer box. Answers will be judged correct if they are within 1 Kcal/mole of the observed value. Be careful to designate negative values for ΔHº. Finally, indicate whether each reaction is endothermic or exothermic by entering E for the former and X for the latter in the Type box.
