Lesson Title: Today we are learning about
How do surface area and concentration affect the rate of a chemical reaction?
Remember to check for PROGRESS
Focus on Knowledge, Skills and Understanding
Success Criteria: You will show your learning by...
  1. Students should be able to predict and explain the effects of changes in the size of pieces of a reacting solid in terms of surface area to volume ratio
  2. Increasing the concentration increases the frequency of collisions and makes the collisions and so increases the rate of reaction.
  3. Students should be able to recall how changing the concentrations of reactants in solution affects the rate of chemical reactions.
  4. Increasing the concentration of reactants in solution, the pressure of reacting gases, and the surface area of solid reactants increases the frequency of collisions and so increases the rate of reaction.
  5. Students should be able to use simple ideas about proportionality when using collision theory to explain the effect of a factor on the rate of a reaction.
  6. Students should be able to predict and explain using collision theory the effects of changing conditions of concentration, pressure and temperature on the rate of a reaction
  7. Students should be able to recall how changing the surface area of solid reactants affects the rate of chemical reactions.

Keywords:
  • Concentration: The amount of a substance per defined space. (2)
  • Pressure: The force applied perpendicular to the surface of an object per unit area over which that force is distributed. (1)

AFL/Key Questions:
  1. How does increasing the surface area to volume ration of a solid reactant affect the rate of a chemical reaction?
    Increasing the surface area to volume ratio will increase the rate of the chemical reaction because the there will be more contact between the reactant particles. Increasing the frequency of successful collisions.
  2. How does increasing the concentration of reactants in reacting gases, and the surface solution, the pressure of area of solid reactants increase the rate of a chemical reaction?
    Increasing the concentration of reactants in solution, the pressure of reacting gases, and the surface area of solid reactants increases the frequency of collisions and so increases the rate of reaction.
  3. How does increasing the concentration of reactants in solution affect the rate of chemical reactions?
    Increasing the concentration of reactants in solution increases the rate of chemical reactions.
  4. How does changing the concentration of a reactant from 1M to 2M affect the rate of a chemical reaction?
    When the reactant concentration is 2M there are twice as many particles to react. This means the time it would take for the same number of successful collisions will half.
  5. How does increasing the concentration of a solution reactant or the pressure of a gas reactant affect the rate of a chemical reaction?
    Increasing the concentration of a solution reactant or the pressure of a gas reactant will increase the rate of a chemical reaction because there would a higher number of particles in the same area, therefore successful collisions between reactants particles will be more frequent, increasing the rate of reaction.
  6. How does increasing the surface area of solid reactants affect the rate of a chemical reaction?
    Increasing the surface area of solid reactants will increase the rate of a chemical reaction.
