What do catalysts do to the activation energy of a chemical reaction?

Answer 1

A chemical catalyst is a substance that lowers the required activation energy of a reaction. The activation energy is the amount of energy required to "activate" or start a process, this can be in the form of many things, such as heat. A chemical catalyst can be seen as a kind of shortcut in a chemical process to speed things up. A catalyst can also be used to increase the activation energy, so that the reaction will slow down. This is useful for slowing down reactions that are normally too fast to witness.

Answer 2

Catalysts lower the activation energy required for a chemical reaction to occur. By providing an alternative reaction pathway with a lower activation energy, catalysts increase the rate of reaction without being consumed in the process.

Answer 3

A catalyst can stop or speed a chemical reaction.

Answer 4

catalyst make reaction faster because of activation energy.

Answer 5

Catalysts lower the activation energy of the chemical reaction. Thus more reactant particles now have the required minimum activation energy and rate of reaction is increased.

Answer 6

Go faster
