WebMar 27, 2024 · Catalytic mechanisms articles from across Nature Portfolio. A catalytic mechanism is the sequence of elementary reactions by which a catalytic reaction proceeds. WebOzone is a relatively unstable molecule that decomposes to yield diatomic oxygen by the reverse of this equation. This decomposition reaction is consistent with the following mechanism: O3 → O2 +O O+O3 → 2O2 O 3 → O 2 + O O + O 3 → 2 O 2. A number of substances can catalyze the decomposition of ozone. For example, the nitric oxide ...

WebReaction Mechanisms and Catalysis.
