Kinetic isotope effect experiment
Web21 feb. 2024 · Through the isotope tracing method, the effect of O 2 on the decomposition reaction (in other words, the contribution to the formation of products) can be intuitively quantified. On this basis, the formation processes of the main oxygen-containing products (CO 2, SO 2, SOF 2, SO 2 F 2) are studied. WebASK AN EXPERT. Science Chemistry 10.a.
