Final answer:
A chemical reaction that involves bond-breaking typically results in the release of energy, often as heat or light. However, whether the reaction is overall energy-releasing or absorbing depends on the balance between the energy required to break the initial bonds and the energy released upon forming new ones. The correct option is 1.
Step-by-step explanation:
A chemical reaction in which bonds are broken is usually associated with the release of energy which occurs because when bonds are broken, energy that was stored in the bonds is released, usually in the form of heat or light. Examples of such reactions include decomposition reactions where a compound is broken down into simpler substances. Conversely, synthesis reactions, where two or more reactants form a new larger molecule, require an input of energy for the bonds to form.
It's important to note that while the breaking of bonds releases energy, the overall reaction can either be exothermic (releasing more energy than is consumed) or endothermic (consuming more energy than is released), depending on the strength of the bonds being broken compared to the new bonds formed in the reaction products.
Hence, Option 1 is correct.
