Here's the chemical equation for this reaction:

2 H₂O₂ → 2 H₂O + O₂

This decomposition can be accelerated by:

* Heat: Higher temperatures speed up the reaction.

* Light: Exposure to light can trigger decomposition.

* Catalysts: Certain substances, like manganese dioxide (MnO₂), can act as catalysts, speeding up the reaction without being consumed themselves.
