Collision Therory Flashcards
1
Q
How does the rate of reaction depend on temperature?
A
Increasing temperature gives particle more energy, therefore go faster and chance of colliding is increased (if not enough energy, particles don’t collide to produce the product)
2
Q
How can the rate of reaction depend on concentration (pressure)?
A
Particles will be more crowded together therefore collide quicker as they are not as far from each other
3
Q
How can the rate of reaction depend on surface area?
A
Smaller particles means the other particles can get to it more easily
4
Q
How does the rate of reaction depend on catalysts?
A
Catalysts increase the speed of reaction without any chemical change
- catalysts work by giving particles a surface to stick on, therefore they do not have to travel
- increases the number of SUCCESSFUL collisions
