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.

What does a catalyst do to the rate of a chemical 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.
What effect does a catalyst have?
a catalyst has no effect in chemical reaction. it only increases or decreases the rate of the chemical reaction.
What is a substance that speeds up the rate ofchemical reaction?
a catalyst
What will change when a catalyst is added to a chemical reaction?
A catalyst speeds up the rate of reaction, and lower the activation energy needed.
What does a catalyst do in a chemical reaction?
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.
What effect does catalyst on a reaction?
A catalyst speeds up the rate of a reaction.
What effect does a catalyst having a reaction?
A catalyst speeds up the rate of a reaction.
What is a substance that speeds up a reaction?
A catalyst is a substance that speeds up the rate of a chemical reaction.
What is a catalyst and why is it important in certain reactions?
a catalyst speeds up the rate of reaction
A substance that speeds up rate of a chemical reaction?
Catalyst, biocatalyst or enzyme.

How do catalyst and inhibtors affect reaction rate?
A catalyst speeds up the reaction and lowers the amount of heat needed.
How catalyst can change the rate of a chemical reaction?
speeds it up or starts it
