One reactant is broken down into two or more products.

Answer 1

This type of reaction is called a decomposition reaction. In a decomposition reaction, a single reactant molecule breaks down into two or more products. This can occur due to various reasons such as heat, light, or the addition of a catalyst. An example of a decomposition reaction is the breakdown of hydrogen peroxide (H2O2) into water (H2O) and oxygen gas (O2).
