| 1. What is the equation for the rate of a reaction? | |
| 2. What happens to a graph of a reaction as the reaction ends? | The gradient decreases until the product produced (or reactant used) reaches a constant value. |
| 3. What are the different ways which one can use to change the rate of a reaction? | |
| 4. How would a reaction's reaction rate graph change if the temperature of the reaction was increased? | |
| 5. How would a reaction's reaction rate graph change if a catalyst was added to the reaction? | |
| 6. How would a reaction's reaction rate graph change the concentration (but not the amount) of one of the reactants was increased? | |
| 7. How would a reaction's reaction rate graph change if a solid reactant was broken into smaller chunks? (Increase in surface area/decrease in particle size) | |
| 8. What is the definition of a catalyst? | Catalysts are substances that speed up chemical reactions but are chemically unchanged at the end of the reaction. The same mass of catalyst will be present at the start and end of a reaction |
| 9. What happens to the rate of a reaction as time goes on? | The rate of reaction decreases as the reaction progresses |
| 10. How would a reaction's reaction rate graph change if the amount of one of the reactants was doubled? |
