A decomposition reaction is a type of chemical reaction in which a single compound breaks down into two or more simpler products. This reaction often requires an input of energy in the form of heat, light, or electricity.
### Example of a Decomposition Reaction:
One common example of a decomposition reaction is the breakdown of hydrogen peroxide (H₂O₂) into water (H₂O) and oxygen gas (O₂):
\[ 2 \, \text{H}_2\text{O}_2 (aq) \rightarrow 2 \, \text{H}_2\text{O} (l) + \text{O}_2 (g) \]
In this reaction, hydrogen peroxide decomposes into water and oxygen, typically catalyzed by a substance like manganese dioxide (MnO₂) or through the application of heat.
