In life terms it is metabolism but you want the term decomposition for chemical reaction. There are synthesis, decomposition, single replacement, and double replacement. Decomposition is the reverse of synthesis.

I hope the question refers to a particular decomposition. Some decompositions are very exothermic and/or exergonic. The explosive decomposition of nitroglycerin and TNT are examples of that. The same applies to synthesis reactions. Not all of them are exothermic.
