rates of reaction
Temperature
Increasing temperature speeds up the reaction.
Decreasing temperature slows the reaction down.
Higher temperature gives particles more energy, so they move faster and collide more often.
More particles have enough energy to overcome the activation energy barrier and react.
Catalyst
Increases the rate of a chemical reaction.
Allows the reaction to happen faster without being used up.
Lowers the activation energy needed for particles to react.
Helps more successful collisions happen in a shorter time.
Concentration
Increasing concentration speeds up the reaction.
Decreasing concentration slows the reaction down.
More particles in the same space means more frequent collisions.
A higher number of successful collisions per second increases the reaction rate.
surface area
Increasing surface area speeds up the reaction.
Decreasing surface area slows the reaction down.
More surface area means more particles are exposed and available to react.
This leads to more frequent and successful collisions between reactant particles.
