I have a question about this problem, because I got that benzene had an energy of 5,580 kJ and that its Kekule structure had an energy of 5,352 kJ. I got the right answer, but I thought that benzene would have a lower energy with resonance than its Kekule structure, because resonance stabilizes the molecule. If someone could help explain this, I would greatly appreciate it!

Check your calculations.

Benzene does have lower energy due to resonance.

These are the values to break the bonds. Higher more positive means more stable.
