Decomposition reactions in chemistry involve a compound breaking down into simpler substances, often requiring energy such as heat, light, or electricity. These reactions are categorized by their energy sources into thermal, electrolytic, and photolytic types. They play a crucial role in both synthetic pathways and natural cycles, including photosynthesis, where photolysis splits water into oxygen and hydrogen.

Decomposition reactions involve the disintegration of a compound into simpler substances through an energy input
Types of Energy
Decomposition reactions can be classified by the type of energy that initiates them, such as thermal, electrolytic, or photolytic
Activation Energy
An external energy source is required to overcome the activation energy barrier and allow the reaction to proceed
Examples include the thermolytic breakdown of potassium chlorate, the electrolytic decomposition of water, and the photolytic decomposition in photosynthesis
