Effect of Temperature on Rate

• What does collision theory state about chemical reactions?

  Chemical reactions can only take place when reacting particles collide with sufficient energy.
• How does the frequency of successful collisions affect the rate of a chemical reaction?

  The rate of reaction increases with the frequency of successful collisions.
• What is the significance of sufficient energy in particle collisions?

  Particles must collide with sufficient energy to react successfully.
• What is activation energy in a chemical reaction?

  • Minimum amount of energy required for particles to react
  • Determines whether a collision is successful
• What does an exothermic reaction indicate about the energy of products compared to reactants?

  The products have less energy than the reactants.
• What happens to the energy of particles during a chemical reaction?

  The energy of particles increases before the reaction completes.
• How does increasing temperature affect the energy and movement of particles?

  It increases both the energy and movement speed of particles.
• How does temperature influence the rate of chemical reactions?

  • Increases the energy of particles
  • Increases the frequency of collisions
  • More particles can overcome activation energy
  • Rate of reaction is proportional to temperature
• What is the relationship between temperature and the rate of reaction?

  The rate of reaction is proportional to the temperature.
