Question
Whose presence causes the decomposition reaction? Can it be considered as an endothermic reaction?

Decomposition reaction takes place by absorption of heat or in presence of sunlight or carried out by electrolysis.
In decomposition reaction, atoms of reactant molecules absorb energy and decompose into small species. Hence, decomposition reaction is considered as an endothermic reaction since heat is absorbed.
