Witryna12 kwi 2024 · The synthesis of adipic acid, which is formed by the reaction of cyclohexene oxidized by hydrogen peroxide (H 2 O 2), is hazardous because of the highly exothermic nature of this reaction and H 2 O 2 decomposition. The objective of this comprehensive study was to investigate and illustrate the effects of sulfuric acid … WitrynaAnswer (1 of 2): Why is the decomposition process exothermic? It’s not. But that simple statement of fact is probably not a very satisfying answer. So let’s take it from the top. What is meant by “decomposition”? A reasonable definition is the conversion of a chemical compound into its element...
