Detailed Solution

concept - If a compound is a complex in nature, it breaks down into simpler compounds, it is called a decomposition reaction.
As seen in the reaction

2 KCl O_{3} (s) \to 2 KCl (s) + 3 O_{2} (g)

potassium chlorate (

KClO 3

) is breaking down to form potassium chloride (

KCl

), and oxygen.
In a combination reaction, two or more reactants join together to form a single product. Thus, the given reaction is not a combination reaction.
In a decomposition reaction, one reactant is decomposed (broken down) into two or more two products. This is what is happening in the given reaction, therefore, it is a decomposition reaction.
In a displacement reaction, one element of the compound is replaced by a similar type of element. Thus, the given reaction is not a displacement reaction.
Hence, the given reaction is a decomposition reaction.
Hence, the correct option is (2).
