2
Q
Factors affection Rate Of Reaction
A
Temperature, Concentration, Surface Area and Catalysts
3
Q
Minimum amount of energy needed to cause a reaction
A
Activation Energy
4
Q
What does a catalyst do
A
Reduces activation energy : collisions more likely to be successful - provides alternative reaction pathway
Speeds up reacction
provides surface for molecules to attach to
5
