| What affects the rate of reaction? | Temperature, concentration, particle size and the use of a catalyst. |
| What is a catalyst? | A catalyst increases the rate of reaction, but is not used up in it. |
| What is the formula for calculating the rate of reaction? | rate = change in volume/change in time |
| Why would a catalyst be used in industry? | It allows the reaction to be preformed at a lower temperature, saving energy and money. |
| How does temperature affect the rate of reaction? | The higher the temperature, the faster the reaction. The lower the temperature, the slower the reaction. |
| How does concentration affect the rate of reaction? | The higher the concentration, the faster the reaction. The lower the concentration, the slower the reaction. |
| How does particle size affect the rate of reaction? | The smaller the particle, the faster the reaction. The bigger the particle, the slower the reaction. |
