5.6.1.3 collision theory and activation energy Flashcards
1
Q
What is collision theory?
A
It explains how various factors affect rates of reactions.
2
Q
What is needed for chemical reactions to occur?
A
Particles colliding with each other and with sufficient amounts of energy.
3
Q
How are you able to increase the frequency for rates of reactions?
A
Increasing:
The concentration of reactants in solution, the pressure of reacting gases, and the surface area of solid reactants.
4
Q
How can you increase the rate of reaction where the collisions are more energetic?
A
Increase the temperature
