What is the effect of a catalyst on a chemical reaction? (2019)

Step 1: Understand what a catalyst is. A catalyst is a substance that speeds up a chemical reaction without being consumed in the process.
Step 2: Learn about activation energy. Activation energy is the minimum energy needed for a reaction to occur.
Step 3: Know how a catalyst works. A catalyst lowers the activation energy required for a reaction.
Step 4: Realize the effect of lowering activation energy. When the activation energy is lower, more molecules have enough energy to react.
Step 5: Conclude the overall effect. Because more molecules can react, the reaction rate increases.
