WebA catalyst in an exhaust system is designed to help reduce harmful emissions that are produced by the engine during the combustion process. The catalyst works by promoting a chemical reaction that converts the … WebMay 1, 2014 · Catalysts are compounds that speed up chemical reactions by lowering the energy barrier between reactants and products. Not only do they save energy, they can also help to produce a pure product instead of a mixture. In the last Avogadro’s lab we saw that enzymes, biological catalysts, do their job very efficiently.

WebPlatinum helps to accelerate this reaction (acting as a catalyst) by binding with the H2 molecule. When the H2 molecule binds to the platinum surface the bond between the two H's in the H2 is weakened (so that each H can form a weak bond with the Pt surface). Platinum is so good at this that the H2 basically falls apart and forms 2 Pt-H bonds. crystal cope caldwell bessemer city nc

WebHydrogen gas (H2) adsorbs ("sticks") to platinum metal, which causes the H-H bond to break as two H-Pt bonds form. This makes it easier to remove an electron from each H atom, generating two H+ from H2. The thing that makes platinum such a good catalyst for this process is that it binds hydrogen gas strongly enough, but not too strongly. Metals ...
