FLASHCARD QUESTION
Front
What is Collision Theory?
Back
Collision Theory states that for a reaction to occur, reactant particles must collide with sufficient energy and proper orientation.
2.
FLASHCARD QUESTION
Front
Define Activation Energy.
Back
Activation Energy is the minimum energy required for a chemical reaction to occur.
3.
FLASHCARD QUESTION
Front
What factors affect the rate of a chemical reaction?
Back
Factors include temperature, concentration of reactants, surface area, and the presence of catalysts.
4.
FLASHCARD QUESTION
Front
Explain the concept of the orientation factor in reactions.
Back
The orientation factor is a measure of how likely it is that colliding particles will be in the correct orientation to react.
5.
FLASHCARD QUESTION
Front
What is the significance of the rate-determining step in a reaction mechanism?
Back
The rate-determining step is the slowest step in a reaction mechanism, which determines the overall reaction rate.
6.
FLASHCARD QUESTION
Front
How does temperature influence reaction rates?
Back
Increasing temperature generally increases reaction rates because it increases the kinetic energy of particles, leading to more frequent and energetic collisions.
7.
FLASHCARD QUESTION
Front
What is the relationship between activation energy and reaction rate?
Back
Higher activation energy typically results in a slower reaction rate, as fewer particles have sufficient energy to overcome the barrier.
