Read each question carefully and provide detailed answers based on your understanding of Collision Theory. Show all work for calculations.
1. According to collision theory, for a reaction to occur, reactant particles must:
Collide with any energy.
Collide with energy less than activation energy.
Collide with sufficient energy and correct orientation.
Collide and have identical shapes.
2. What happens to the rate of reaction if the temperature is increased?
It decreases because particles move slower.
It increases due to more frequent and energetic collisions.
It remains unchanged.
It increases due to an increase in activation energy.
3. The minimum amount of energy required for a reaction to occur is called the .
4. For a successful collision, the colliding particles must have the correct in addition to sufficient energy.
5. Increasing the concentration of reactants will decrease the frequency of collisions.
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 role of molecular orientation in a successful collision. Provide an example.
9. Analyze the diagram below, which illustrates how molecular orientation can affect the outcome of a collision between two molecules, A-B and C. Explain why the first collision is successful while the second is not, in terms of collision theory.
