Activation energy is lowered to speed up a chemical reaction.
speed up chemical reaction because of the lowered activation energy
to speed up a chemical reaction
chemical reaction
A catalyst can speed up a chemical reaction.
Anything that is added to a chemical reaction that's intended to speed up the reaction - is a catalyst.
Catalysts speed up the chemical reaction.
Enzymes are proteins that speed up chemical reactions.
Enzymes are proteins which speed up chemical reactions.
The particle size is decreased so that you can speed up a chemical reaction. Proteases is the enzymes that break down proteins.
Speed up the rate of a chemical reaction
No a catalyst is unchanged by a chemical reaction, it does however serve to speed up the rate of the reaction.
Increasing the pressure on a reaction involving reacting gases increases the rate of reaction. Changing the pressure on a reaction which involves solids or liquids has no effect on the rate of reaction.
