- Chemistry Unit 2 AQA
- Rates of reaction
- Temperature increases the rate of reaction
- Particles move more quickly and they have the activation energy or greater
- Concentration increases the rate of reaction
- There are more particles and collisions are more frequent
- Pressure increases the rate of reaction
- There are more particles and collisions are more frequent
- Particle size
- There is a larger surface area for reactions and particles collide more frequently
- Catalyst
- Catalysts increase the rate of reaction without being used up. They do this by lowering the activation energy needed.
- Temperature increases the rate of reaction
