How do catalysts affect reaction rate?

What role do catalysts play in chemical reactions?

Catalysts speed up chemical reactions without being consumed. They lower the activation energy needed.

Can you give me an example of a catalyst in a reaction?

Sure! An example is the enzyme catalase, which speeds up the decomposition of hydrogen peroxide into water and oxygen.

How do catalysts lower activation energy?

Catalysts provide an alternative pathway for the reaction with a lower activation energy, making it easier for reactants to convert to products.

Are there any downsides to using catalysts?

Yes, some catalysts can be expensive or may require specific conditions to work effectively, which can limit their use.
