chemical reactions could be classified based on different criteria. For example exo and endothermic depending on the energy which is absorbed and given off. The other criterion is the number of product that is produced, displacement (single, double) composition and decomposition reaction. The third one is depending on its reversibility (the direction in which the reaction go on), reversible and irreversible.
