Catalysts.

Question 1

What are Catalysts in terms of the rate of reaction?

Answer 1

• Increases the rate of chemical reactions.
• They are not used up in chemical reactions.
  Useful: Allows reactions to take place quickly, without needing to increase the temperature so saves money.
• Reused.

Question 2

What does this look like in an activation profile?

Answer 2

• Catalysts provide a different pathway for the reaction by directing a route with a lower activation energy.
• Requires less energy to cross the activation barrier so more successful collisions per seconds.

Question 3

Key Points about Catalysts?

Answer 3

• We do not include Catalysts in chemical equations of the reaction as they are not used up and are not a reactant.
• Different reactions need different catalysts.
• Enzymes act as catalysts in living organisms.

Question 4

Key Points about Catalysts:

Answer 4

• Do not include catalysts in chemical equations for reactions are they are not used up in a reaction and are not reactants.
• Different reactions need different catalysts.
• Enzymes
