Reaction Rate

1
Reaction Rate

• Chapter 17.1

2
Reaction Rate

• As time passes
• reactant decreases
• product increases
• Reactants
• ?
• Products

3
Collision Theory

• A reaction will occur if particles collide
• with correct orientation
• With sufficient kinetic energy

4
Factors Affecting Rxn Rate

• Temperature
• As temperature increases rxn rate increases
• Concentration
• As concentration increases rxn rate increases
• Particle Size
• Smaller particles have more surface area
• As particle size decrease, surface area
  increases, rxn rate increase

5
Other Factors Affecting Rxn Rate

• Catalysts
• Increase rate of reaction by lowering the
  activation energy
• Not used up in the reaction
• Inhibitor
• Interferes with catalyst
• Reduce catalyst function slowing or stopping the
  reaction
