Lesson Title: Today we are learning about
What is atom economy?
Remember to check for PROGRESS
Focus on Knowledge, Skills and Understanding
Success Criteria: You will show your learning by...
  1. The atom economy (atom utilisation) is a measure of the amount of starting materials that end up as useful products.
  2. The percentage atom economy of a reaction is calculated using the balanced equation for the reaction as follows: Relative formula mass of desired product from equation / Sum of relative formula masses of all reactants from equation ? 100
  3. Students should be able to calculate the atom economy of a reaction to form a desired product from the balanced equation
  4. (HT only) explain why a particular reaction pathway is chosen to produce a specified product given appropriate data such as atom economy (if not calculated), yield, rate, equilibrium position and usefulness of by-products.

AFL/Key Questions:
  1. (Chem only) What is atom economy a measure of?
    The amount of starting materials that end up as useful products.
  2. (Chem only) What is the formula for calculating percentage atom economy?
    The percentage atom economy of a reaction is calculated using the balanced equation for the reaction as follows: Relative formula mass of desired product from equation / Sum of relative formula masses of all reactants from equation ? 100
  3. (Chem only) Hydrazine (N2H4) is used in some rocket fuels. Two different methods can be used to manufacture hydrazine. The reactions are: NH2Cl NH3 ? N2H4 HCl 2NH3 H2O2 ? N2H4 2H2O Calculate the atom economy for each reaction
    1) Mr of N2H4 = 32 2) Sum of Mr all reactants in equation 1= 68.5 3) (32 / 68.5 ) x100 46.7% 4) Sum of Mr all reactants in equation 2 = 68 5) (32/68) x 100 = 47%
  4. (Chem only) How can a chemist in a chemical plant that makes rocket fuel prevent waste products being formed?
    (HT) A chemist can prevent waste rocket fuel being formed by Choose a reaction with few/no other products.
