C2 - Collision Theory Flashcards
1
Q
What is ‘rate of reaction’?
A
The rate at which a reaction takes place
2
Q
What factors affect the rate of a reaction?
A
Temperature
Concentration (solution)
Surface area (solid)
3
Q
What must happen for a reaction to occur?
A
Particles must collide with each other
4
Q
What determines whether a collision is ‘successful’ or not?
A
Whether or not enough energy is present to break the bonds
5
Q
What happens if the rate of reaction is increased?
A
Then collisions become more frequent
6
Q
What does a low concentration mean in a chemical reaction?
A
There will be less solute
The reaction will be slower
Less collisions
7
Q
What does a high concentration mean in a chemical reaction?
A
There will be more solute
The reaction will be faster
More collisions
