Step 1
It has a lower average bond energy.
Answer
Ozone (O₃) has a lower average bond energy compared to molecular oxygen (O₂). This means that the bonds in ozone are weaker and easier to break. The O-O bond in ozone is notably weaker due to the presence of a resonance structure, allowing for easier decomposition into molecular oxygen and free oxygen atoms.
