Answer:

Decomposition reactions are usually endothermic because they involve breaking of bonds. Breaking bonds requires an input of energy, while forming bonds releases energy. ... But there are decomposition reactions which are exothermic like decomposition of hydrogen peroxide.

Decomposition reactions are Endothermic, as energy in the form of mainly heat(thermal decomposition), light(photolytic decomposition), electricity(electrolytic decomposition), or catalyst (catalytic decomposition) is required to break or decompose the substance down into its constituent atoms or molecules...
