1. Which of the following best defines bond energy?
The energy released when a bond is formed.
The energy required to break one mole of a particular bond in the gaseous state.
The total energy of all bonds in a molecule.
The energy associated with intermolecular forces.
2. High bond energy generally indicates:
A weak bond.
A stable bond.
A long bond length.
Easy to break.
3. Bond breaking is an process, meaning it requires energy input.
4. The energy released when bonds are formed is always to the energy required to break them.
5. A triple bond generally has a higher bond energy than a single bond between the same two atoms.
True
False
6. Explain the relationship between bond length and bond energy.
7. Observe the diagram below, which illustrates covalent bond formation. Using your understanding of bond energy, describe what happens to energy during bond formation and why it's a favorable process.
8. Given the following average bond energies:
C-H: 413 kJ/mol
O=O: 498 kJ/mol
C=O: 799 kJ/mol
O-H: 463 kJ/mol
Calculate the enthalpy change (ΔH) for the combustion of methane (CH₄) based on bond energies:
CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(g)
