Photodecomposition reaction
WebApr 5, 2024 · A photodecomposition reaction is a sort of decomposition process in which the reactant absorbs energy from photons and breaks down into its parts. The breakdown of dioxygen and an oxygen radical, as indicated by the chemical equation below, is an example of a photodecomposition process. Eg.\[ O_{3} + hν \rightarrow O_{2} + O\]. Replacement ... WebThe reactions of acetone vapor with nitrogen oxides, hydroxyl radicals (OH), singlet molecular oxygen (1 ... When distilled water or natural water containing acetone was exposed to sunlight for 2-3 days, no photodecomposition of acetone was observed (Rathbun et al. 1982). Therefore, photolysis of acetone in water is not an important process.
