C-collision Models

Realize the factors of a collision which vary the reaction. Be able to draw a picture of the two types of collisions that do not produce a reaction and the type of collision that does.


Questions and Answers
  • 1. 
    Why don't collisions occur when molecules react in low temperatures?
    • A. 

      The orientation of the molecules are wrong

    • B. 

      The orientation of the molecules are correct

    • C. 

      The molecules are moving too fast to be able to collide

    • D. 

      The molecules are moving too slow to be able to collide

  • 2. 
    What are the factors that affect the occurrence of collisions?
    • A. 

      Temperature and orientation

    • B. 

      Concentration, orientation, and temperature

    • C. 

      Energy and concentration

    • D. 

      Orientation

  • 3. 
    How does having a higher concentration of molecules affect the frequency of collisions?
    • A. 

      There are less collisions occuring because since there are more molecules present, they move slower.

    • B. 

      There are more molecules which causes more collisions to occur and more reactions to take place.

    • C. 

      There are no collisions taking place because there is no room for them to move around.

    • D. 

      There is no change. Collisions happen at a constant pace and the concentration of molecules doesn't affect collisions.

  • 4. 
    If there were hydrogen and oxygen molecules colliding together, what new molecular compound would they form after reacting?
    • A. 

      H2O2

    • B. 

      OH

    • C. 

      H2O

    • D. 

      All of the above

  • 5. 
    What is the collision model?
    • A. 

      Molecules colliding to reach equilibrium

    • B. 

      Molecules colliding to lower the activation energy

    • C. 

      Molecules colliding to form a reaction

    • D. 

      Molecules colliding to speed up a reaction
