Collision Theory

HideShow resource information
What 4 things does rate of reaction depend on?
Temperature, Concentration, Catalyst, Surface area
1 of 9
When the temperature is increased, the particles...
... more faster.
2 of 9
When moving faster, there's a higher chance of them...
... colliding more frequently.
3 of 9
The faster they move...
... the more energy they have.
4 of 9
If a solution has a higher concentration, it means that...
... there are more particles of reactant, making the collision more likely.
5 of 9
You can increase the surface area by...
... crushing the solid into a powder form.
6 of 9
Having a bigger surface area allow for...
... more collisions to take place as there's more area to work with.
7 of 9
A catalyst is...
... a substance which increases the speed of a reaction without being used up in the reaction.
8 of 9
A catalyst increases the rate of reaction because...
... it provides a surface for the reacting particles to stick to so they can bump into each other successfully.
