Flashcards on Collision Theory

Click on the flashcard to see the answer


What is collision theory?

Collision theory explains how chemical reactions occur and why reaction rates differ.

Who proposed the collision theory?

The collision theory was proposed by Max Trautz and William Lewis in 1916.

What are the key components of collision theory?

The key components are collision frequency, orientation, and energy.

How do temperature and concentration affect collision theory?

Higher temperature and concentration increase the chances of successful collisions.

Explain the concept of activation energy in collision theory.

Activation energy is the minimum energy required for a successful reaction to occur.

What role do catalysts play in collision theory?

Catalysts lower the activation energy barrier, increasing the rate of reaction.

How does molecular size impact collision theory?

Smaller molecules have higher collision frequencies due to their size.

What is the significance of proper molecular orientation in collision theory?

Correct orientation is needed for effective collisions to lead to a reaction.

Describe the relationship between reaction rate and collision theory.

The reaction rate is directly proportional to the number of successful collisions.

How does the nature of reactants influence collision theory?

Different reactants have varying collision frequencies based on their structure and properties.
