An example of an electrolytic decomposition reaction is the electrolysis of water, which can be represented by the given chemical equation: 2H 2 O→ 2H 2 + O 2. Reactions in which a compound decomposes because of sunlight are known as Photolysis or Photo Decomposition Reaction. This reaction is one of the exceptions to the endothermic nature of decomposition reactions. Textbook Solutions 6352. For example, decomposition of sodium chloride occurs on passing electric current through its aqueous solution. Decomposition Reaction is the separation of a substance or material into two or more substances or materials that might differ from each other and from the original or unique substance. Adjust the resistance of the rheostat using the slider. CISCE ICSE Class 8. Example: from the naturally occurring ore of zinc, zinc carbonate is first decomposed to give zinc oxide and then reduced to obtain zinc metal. Electrolytic Decomposition. Concept: Concept of Chemical Reactions. 4 N H 3 (g) + 5 O 2 (g) → 4 N O (g) + 6 H 2 O (g) is an example of displacement as well as redox reaction. Electrolysis reactions will not run unless energy is put into the system from outside. Answer: In this type of reaction, the reactant is decomposed by applying electricity. In this type of chemical reaction one substance is divide into two or more new substance under control condition.
