  • 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.
