effect of catalyst

• What does collision theory state?

  Reactions occur when particles collide with energy
• What determines the rate of a chemical reaction?

  The frequency of successful collisions
• What is activation energy?

  The minimum energy needed for particles to react
• How does a catalyst affect the activation energy in a reaction?

  It provides a pathway with lower activation energy
• What is the definition of a catalyst?

  Increases reaction rate without being used up
• Why are catalysts important in chemistry?

  They allow quick reactions without temperature increase
• Can catalysts be reused after a reaction?

  Yes, they are not used up
• How do catalysts increase the rate of reaction?

  By allowing more particles to collide successfully
• Are catalysts included in the chemical equation for a reaction?

  No, they are not included
• Do different reactions require different catalysts?

  Yes, different reactions need different catalysts
• What role do enzymes play in living organisms?

  They act as catalysts
• What is the effect of catalysts on the rate of chemical reactions?

  • Catalysts increase the rate of reactions
  • They provide a lower activation energy pathway
  • More particles can collide successfully
  • They are not consumed in the reaction
• What are the key points about catalysts that need to be learned?

  1. Catalysts are not included in chemical equations
  2. Different reactions require different catalysts
  3. Enzymes serve as catalysts in living organisms
