answered-by-expert Expert Answer
(1) Thermal Energy-  Heat is required for thermal dissociation kind of chemical change. This chemical change is known as Thermal decomposition. For e.g-
                                              italic 2 K C l O subscript italic 3 italic space stack italic rightwards arrow italic 2 with italic increment on top K C l italic plus italic 3 O subscript italic 2
(2) Light Energy- Few chemical changes take place in presence of u-v light. This chemical change is known as Photo-decomposition. For e.g.-
                                                2 H B r space rightwards arrow with straight u minus straight v space light on top space straight H subscript 2 plus space Br subscript 2
(3)Electric Energy- When Electricity is nedded for decomposition this kind of decomposition is known as Electrolytic- decomposition. For e.g-
                                               2 straight H subscript 2 straight O rightwards arrow with electric space current on top space space 2 straight H subscript 2 plus straight O subscript 2
