I had this question in chemistry, and i'm sure it's a decomposition reaction.
I believe an oxidation reaction is occurring
The reaction KBrO 3 ( s ) → KBr ( s ) + O 2 ( g ) is a decomposition reaction because a single compound, potassium bromate, breaks down into two simpler products: potassium bromide and oxygen gas. These types of reactions typically occur due to heat or other forms of energy. Thus, this is classified as a decomposition reaction in chemistry.
