  1. 3.7 Energy Distribution 3.7.1 Distribution Graphs LO: I understand what is meant by a distribution diagram

  2. Collisions on the right of the Ea (shaded area) have enough energy to form an . Collisions on the left of Ea don’t have enough . activated complex energy faster The larger the shaded area, the the reaction rate. LO: I understand what is meant by a distribution diagram.

  3. 3.7.2 Concentration and Temperature LO: I understand how concentration and temperature affect a distribution diagram.

  4. Concentration: With increased concentration: • there are molecules present. more greater • more molecules have energy than Ea. faster • the rate of reaction is . LO: I understand how concentration and temperature affect a distribution diagram.

  5. Temperature: With increased temperature: • the kinetic energy of the molecules . increases right • the graph spreads to the . greater • more molecules have energy than Ea. faster • the rate of reaction is . LO: I understand how concentration and temperature affect a distribution diagram.

  6. 3.7.3 Catalytic Effect LO: I understand how a catalyst affects a distribution diagram.

  7. Using a catalyst: • the activation energy is . lower larger • the shaded area is . greater • more molecules have energy than Ea. faster • the rate of reaction is . LO: I understand how concentration and temperature affect a distribution diagram.
