Q
Q: What is the primary role of a catalyst in a chemical reaction?
Solution:
A catalyst lowers the activation energy of a reaction, thereby increasing the rate without being consumed.
Steps: 5
Show Steps
Step 1: Understand that a chemical reaction needs energy to start. This energy is called activation energy.
Step 2: Know that a catalyst is a substance that helps a reaction happen faster.
Step 3: Learn that a catalyst lowers the activation energy needed for the reaction.
Step 4: Realize that by lowering the activation energy, the catalyst allows more reactions to occur quickly.
Step 5: Remember that a catalyst is not used up in the reaction, meaning it can be used again.
