What factors affect the rate of a reaction?
Temperature, the presence of a catalyst, concentration, pressure and surface area
1 of 5
How do you find the rate of a chemical reaction?
Amount of reactant used / time
2 of 5
What is the activation energy?
The minimum amount of energy particles must have to react
3 of 5
Why does increasing temperature increase rate of reaction?
The particles have more energy and so have more energetic and successful collisions
4 of 5
Why are catalysts useful in industry?
They are not used up in reactions so can be used again, and saves energy and therefore saves costs
