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.
Because it lowers the activation energy needed to "start" the reaction.
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 has no effect in chemical reaction. it only increases or decreases the rate of the chemical reaction.

A catalyst speeds up the rate of reaction, and lower the activation energy needed.
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.
