Which of the following statements is/are correct? 1. The bond energy, BE(Cl-Cl), in Cl2 is 244 kJ mol-1 since ∆H°f {Br,atomic,g) = 122 kJ mol-1. 2. A compound has a ∆H°f , calculated from average bond energies, of -20 kJ mol-1, whereas its experimental ∆H°f is -80 kJ mol-1. This compound is less stable than predicted by its Lewis structure. 3. A gas phase chemical reaction is found to be exothermic. This means that the sum of the bond energies...
