A catalyst speeds up a reaction rate because it lowers the activation energy.
The activation energy is the amount of energy required to start a reaction. If less energy is needed, then the same amount of energy can react more times.

A catalyst is a substance that speeds up the rate of a chemical reaction without changing the substance. It does this by reducing the minimal reaction energy. A catalyst is not used up in a reaction therefore they last indefinitely.
A catalyst speeds up a chemical reaction by lowering the activation energy required for the reaction to occur. It does so by providing an alternative reaction pathway that requires less energy to initiate the reaction. The catalyst itself remains unchanged at the end of the reaction and can be used over and over again.
Reduces the activation energy of the reaction, which speeds up the progress of the reaction It increases the rate of a chemical reaction. However a true catalyst is not consumed in the reaction.
None: The catalyst remains unchanged, but the catalyst also speeds up the reaction.
A catalyst speeds up the rate of a reaction.
A catalyst speeds up the rate of a reaction.
a catalyst speeds up the rate of reaction
A catalyst is a substance that speeds up the rate of a chemical reaction.
A substance that speeds up a chemical reaction is known as a CATALYST.
a catalyst
A catalyst speeds up the reaction and lowers the amount of heat needed.
A substance that speeds up the rate of a chemical reaction without being consumed in the process is called a catalyst. Catalysts provide an alternative pathway with lower activation energy for the reaction to occur, increasing the reaction rate without being altered themselves.
