What Affects Rate of Reaction?

Causes

  • Higher concentration
  • Higher temperature
  • Larger surface area
  • Catalysts

Effects

  • More particles are able to react, so there is more chance of a reaction happening and more collisions.
  • Particles move faster, more successful collisions as particles harder and more frequently
  • More particles are able to react so there are more chance of a reaction happening and more frequent collisions.
  • Less energy needed to have the reaction, so more successful reactions

Overall summary

Higher concentration, higher temperature, a larger surface area, and using catalysts all increase the rate of reaction.
