3. KEYWORDS: rate of reaction, product, reactant, time KEYWORDS: rate of reaction, product, reactant, time Understand what is meant by rate of reaction ALL – State the definition of a rate of reaction MOST – describe reactions that occur slowly and quickly SOME – explain how rate of reaction is calculated Starter Make a list of chemical reactions that you see in every day life

4. EVERYDAY CHEMICAL REACTIONS Make a list of everyday chemical reactions

5. Rate of reaction Reactions happen at different speeds. A firework relies on a chemical reaction that happens in milliseconds whereas rusting is a chemical reaction between a metal and oxygen which can take years to happen LO: Understand what is meant by rate of reaction

6. Rate of reaction The rate of a reaction is how quickly the reactants are turned into products LO: Understand what is meant by rate of reaction

7. MUST LEARN THESE: LO: Understand what is meant by rate of reaction Rate of Reaction = Amount of reactant used _______________ Time taken Rate of Reaction = Amount of product made _______________ Time taken

8. Practical results – measuring rate of reaction LO: Understand what is meant by rate of reaction Time (s)Mass of mixture (g) Mass of product (g) 027.00 3025.9 6025.3 9025.0 12024.9 15024.9 18024.9

9. Draw a line graph. A-A*: Draw a line of best fit for your results and use your graph to calculate the rate of reaction. B: Draw a line graph of your results and explain why the rate changes throughout. C: Use your results to state where the maximum rate of reaction occurs. LO: Understand what is meant by rate of reaction
