1. REACTION RATES

2. Reaction Rate
The rate of disappearance of a reactant or appearance of a product

3. Concentration Concentration in terms of Molarity
How much chemical per liter solution
Increasing concentration increases the reaction rate

4. Stirring
Stirring a solution makes the reactants contact each other more often
Increase stirring = increased reaction rate

5. Temperature
Increasing temperature increases the average kinetic energy of particles
This increases the number of collisions between reactants
Increase temperature = increase rate of reaction

6. So if we want to increase reaction rate…
What 3 things should we do?
Increase temperature
Increase stirring

7. Surface Area More surface area increases contact between reactants
Increasing surface area = increases reaction rate

8. Catalyst
A substance that increases reaction rate without being consumed during the reaction
