Oct 21, 2016 · The investigation of oxidation reactions on Pt/Rh gauze catalysts is challenging due to their high reaction rate and complexity. Concentration profiles of OH • radicals, which represent an indicator species for these reactions, are measured for the catalytic combustion of methane in a single Pt‐gauze reactor. CFD simulations of the profiles show that the reaction proceeds partly at the Pt ...

Reactants and Products in Chemical Reactions - dummies

In a chemical reaction, substances (elements and/or compounds) called reactants are changed into other substances (compounds and/or elements) called products. You can't change one element into another in a chemical reaction — that happens in nuclear reactions. Instead, you create a new substance with chemical reactions. A number of clues show that a chemical reaction [.]
