Hydrogen peroxide decomposes according to the equation . Using bond energies, a student finds that more energy is released in forming bonds in the products than is absorbed in breaking bonds in the reactant. What type of reaction is this?
- Exothermic, because energy is released overall.
- Endothermic, because bonds are broken.
- Endothermic, because energy is released overall.
- Neither exothermic nor endothermic, because energy changes cancel exactly.
