Read each question carefully and provide your best answer based on your understanding of Collision Theory.
1. Which of the following is NOT a fundamental postulate of Collision Theory?
Reactant particles must collide.
Collisions must have sufficient energy.
Collisions must have the correct orientation.
Increasing temperature always increases reaction rate.
2. What is the minimum energy required for a reaction to occur called?
Kinetic energy
Potential energy
Activation energy
Threshold energy
3. According to Collision Theory, an effective collision must have both sufficient energy and proper .
4. Increasing the concentration of reactants will generally the reaction rate because it leads to more frequent collisions.
5. All collisions between reactant particles lead to a chemical reaction.
True
False
6. A catalyst increases the reaction rate by increasing the activation energy.
True
False
7. Explain how increasing the surface area of a solid reactant affects the rate of reaction according to Collision Theory.
8. Describe the concept of 'molecular orientation' in the context of effective collisions.
9. Examine the diagram below illustrating molecular collisions. Based on Collision Theory, which collision is most likely to result in a reaction? Justify your answer.
