Answer with Explanation:

Hydrogen peroxide is considered<em> "unstable,"</em> thus, storing it in the refrigerator provides two advantages:

1. It slows down thermal decomposition.

  • The rate of decomposition slows down when the temperature is lowered. It increases when the temperature rises.

2. It prevents photolytic decomposition.

  • Photolytic decomposition happens when hydrogen peroxide is exposed to sunlight or bright light. It therefore increases the rate of reaction. Therefore, hydrogen peroxide should be stored in a <em>cool and dark place</em>, such as the refrigerator.
