Question

splitting of single reactant into two or more simpler products is called --------------

Answer 1

Decomposition (or analysis)

In a decomposition reaction a single substance is broken down into two or more simpler substances. These simpler substances may either be elements or compounds. Most decomposition reactions are endothermic (absorb energy during the reaction). The energy for the endothermic reactions is usually supplied as heat or electricity. Sometimes, however, the reaction can be exothermic. An example of this is the breakdown of unstable compounds.

Several examples of decomposition are:

2H2O à 2H2 + O2 * Decomposition of water by an electric current, a reaction also called
