Cl2 has a longer, weaker bond than Cl2+ (Cl2: 1.988 Å, Cl2+ : 1.8917 Å). Furthermore,...
Cl2 has a longer, weaker bond than Cl2+ (Cl2: 1.988 Å, Cl2+ : 1.8917 Å). Furthermore, Cl2+ has higher bond dissociation energy (Cl2: 57.18 kcal/mole, Cl2+ : 99.2 kcal/mole). Use molecular-orbital theory to predict the bond order for each of these molecules and explain why Cl2+ has higher bond dissociation energy.

According to your textbook, the bond energies for a C=O bond and an O=O bond are 803 and 498 kJ per mole, respectively. Double-check the table to make sure that these values are correct. Based on those values for bond energies, calculate the energy released in this reaction. Your answer should have units of kJ per mole of CO2 formed. C + 02 → CO2
