Worksheet: Catalyzed Reaction Profiles

In this worksheet, we will practice drawing and identifying schematic reaction profiles for catalyzed reactions with a range of catalytic mechanisms.


Illustrated in the plot is the energy change during a chemical reaction.

How many transition states exist in this reaction?

How many intermediates exist in this reaction?

Estimate, to the nearest 10 kJ/mol, the activation energy for this reaction.

Catalyzing a reaction reduces the activation energy. Which of the following reaction profiles could be obtained by performing this reaction in the presence of a catalyst?

  • A
  • B
  • C
  • D
  • E
