Collision Theory and Catalysts Flashcards
1
Q
What is the collision theory?
A
That a reaction occurs when particles collide with enough activation energy to react.
2
Q
How does the collision theory increase the rate of reaction?
A
More collisions per second means the rate increases
3
Q
Define activation energy
A
The minimum amount of energy required in a collision for particles to react.
4
Q
What 4 things are needed to increase the amount of collisions?
A
- Higher temp
- Higher pressure
- Larger surface area
- Catalysts (provide an active site)
5
Q
What are the positives of using catalysts in the industry?
A
Saves energy
Saves time
Saves money
6
Q
What are the negatives of using catalysts in the industry?
A
Expensive
Can get destroyed so need repairing
Different reactions need different catalysts - specific
