Rate and Extent of Chemical Change

Rate of Reaction: How much reactant is used up in one second

Collision Theory:

• How often particles collide, the more collisions there are the faster the reaction is 
• The energy transferred during a collision

Factors affecting the Rate of Reaction: 

Temperature: When temp increases, particles move faster and collide more frequently therefore more energy is produced

Concentration: Increasing concentration  means there are more particles knocking about therefore collision occur more frequently

Surface Area: Surface area increases, particles have more space to knock around meaning collision occur more frequently

Catalyst: Catalysts speed up the rate of reaction through reducing the amount of activation energy  which is the minimum amount…
