Catalysts are used to speed up chemical reactions, while remaining chemically unchanged at the end of the reaction.
Only a small amount of catalyst is required to increase the rate of reaction. Increasing the amount of catalyst will need increase the rate beyond a specific point.
Below are examples of catalysts and the reactions they catalyse:
Catalytic converters are used to reduces the release of toxic gases from exhaust pipes, which decreases the chances of us getting sick.
As you can see from the diagram above, catalytic converters…
Convert nitrogen oxides to nitrogen and oxygen
Convert carbon monoxide to carbon dioxide
Converts hydrocarbons into carbon dioxide and water
