11. Bonding & Molecular Structure

Which of the following best describes bond dissociation energy?

Use bond energies to estimate the enthalpy change for the formation of HBr(g) from H2(g) and Br2(g). Given: BE(H-H) = 436 kJ/mol, BE(Br-Br) = 192 kJ/mol, BE(H-Br) = 366 kJ/mol.

Which of the following bonds has the longest bond length?

What is the bond energy per mole required to break all the bonds in a molecule of oxygen (O_2) under standard conditions?
