Read each question carefully and answer to the best of your ability. Show all your work for calculations.
1. What does Collision Theory state is necessary for a chemical reaction to occur?
Reactants must be in the same phase.
Reactant particles must collide with sufficient energy and correct orientation.
A catalyst must be present.
The reaction vessel must be sealed.
2. What is activation energy?
The energy released during a reaction.
The minimum energy required for a reaction to occur.
The energy of the products.
The energy of the reactants.
3. According to Collision Theory, increasing the temperature of a reaction will generally the reaction rate because it increases the frequency and energy of collisions.
4. For a collision to be effective, particles must collide with sufficient energy and the correct .
5. All collisions between reactant particles lead to a chemical reaction.
True
False
6. A catalyst works by increasing the activation energy of a reaction.
True
False
7. Explain how increasing the surface area of a solid reactant affects the rate of reaction based on Collision Theory.
8. Describe the two main requirements for an effective collision between reactant particles.
