Worksheet: The Collision Theory

Q1:

Collision theory states that chemical reactions occur when particles (for example, atoms or molecules) collide. Which of the following, according to collision theory, does not play a part in determining the rate of a reaction?

  • A The energy with which particles collide
  • B The frequency with which particles collide
  • C The activation energy for the reaction
  • D The number of particles analyzed

Q2:

Which one of the following would not increase the rate of a reaction, according to collision theory?

  • A Increasing the temperature
  • B Increasing the pressure
  • C Using a catalyst
  • D Using a differently shaped container with the same volume
  • E Increasing the surface area of particles

Q3:

Which one of the following would not increase the rate of a reaction, according to collision theory?

  • A Particles having more energy
  • B Particles colliding more frequently
  • C A higher temperature
  • D A higher activation energy
  • E A higher particle concentration
