1.	Following reaction is used for the preparation of oxygen gas in the laboratory. Heat2KClO3(s) \(\underset{Catalyst}{\stackrel{Heat}{\rightarrow}}\) 2KCl(s) + 3O2(g)Which of the following statement(s) is (are) correct about the reaction? A. It is a decomposition reaction and endothermic in nature. B. It is a combination reaction. C. It is a decomposition reaction and accompanied by the release of heat. D. It is a photochemical decomposition reaction and exothermic in nature.
Answer» Since the reaction involves the breaking down of a single reactant molecule into multiple products, it is a decomposition reaction. Moreover it involves the absorption of heat, so it is also an endothermic reaction.
