Explain decomposition reaction with help of heat, electricity and sunlight
Dear student, Decomposition reaction is the one in which a single compound breaks down into two or more than two elements or new compounds. Decomposition in presence of heat is called thermal decomposition: CaCO3 -------> CaO + CO2. Decomposition in presence of electricity is called electrolytic decomposition: 2H2O --------> 2H2 + O2. Decomposition in the presence of sunlight is called photodecomposition reaction: 2H2O2 -------> 2H2O + O2. Regards,
