1

What is Rate of Reaction

Change in concentration
Time

2

How does Concentration affect the rate of a chemical reaction.

There are more molecules per unit volume so are more likely to collide successfully.

3

How does Temperature affect the rate of a chemical reaction.

Molecules have more kinetic energy so there are more frequent collisions and more effective collisions as they have sufficient energy.

4

How does Catalyst affect the rate of a chemical reaction.

Lowers the activation energy so more molecules have sufficient energy to have an effective collision and react.

5

How does Surface area affect the rate of a chemical reaction.

It has a larger surface for collisions so there are more effective collisions.
