Question 1.
What must reactants do to form products according to collision theory?
Show hintHide hint
Think about what needs to happen for a reaction to begin.
Question 2.
What is activation energy?
Show hintHide hint
Consider it as a barrier that needs to be overcome for a reaction.
3Question 3.
What is required for an effective collision to occur?
- A. High pressure
- B. Sufficient energy and proper orientation
- C. Reactants in solid state
Show hintHide hint
Think about what makes a collision successful in forming products.
4Question 4.
True or False: Activation energy is not important for the rate of reactions.
- True
- False
Show hintHide hint
Can't form products without overcoming a certain energy barrier.
Question 5.
A reaction between hydrogen and oxygen to form water requires specific conditions to proceed. If a catalyst is added to the reaction, explain how this impacts the activation energy and the rate of the reaction. Provide a detailed comparison with the original reaction without the catalyst.
Show hintHide hint
Think about how catalysts change the energy barrier for reactions.
Question 6.
You are studying the decomposition of hydrogen peroxide. Explain how adjusting the temperature impacts the rates of reaction and describe in detail using collision theory.
Show hintHide hint
How do temperature changes relate to particle motion and collisions?
