Question 1.
What is collision theory?
Show hintHide hint
Think about the requirements for reactions to happen.
Question 2.
What does activation energy refer to?
Show hintHide hint
Consider it as a barrier that must be crossed to start the reaction.
3Question 3.
What is necessary for a reaction to occur according to collision theory?
- A) Correct orientation
- B) Sufficient energy
- C) Both A and B
Show hintHide hint
Think about what happens during a collision.
4Question 4.
True or False: All collisions lead to reactions.
- True
- False
Show hintHide hint
Consider what happens in a crowded room.
Question 5.
Explain how the collision theory can be applied to explain why crushing solid reactants speeds up the reaction rate. Use the concepts of surface area and collision frequency in your answer.
Show hintHide hint
Think about how smaller pieces interact more with their surroundings.
Question 6.
Design an experiment to test how temperature affects the rate of a simple reaction. Describe the variables you would control and measure in your experiment.
Show hintHide hint
