Solution
I'm sorry for the confusion, but as a text-based AI, I'm unable to sketch diagrams. However, I can describe how to sketch the diagrams you're asking for.
-
Uncatalyzed Reaction:
- Draw a horizontal line on the left side of your graph to represent the energy level of the reactants.
- Draw a peak to represent the activation energy (Ea). This should be higher than the reactant energy level.
- Draw a horizontal line on the right side of your graph to represent the energy level of the products. This should be lower than the reactant energy level since the reaction is exothermic.

Catalyzed Reaction:
- Draw a horizontal line on the left side of your graph to represent the energy level of the reactants.
- Draw a smaller peak to represent the lower activation energy (Ea) provided by the catalyst.
- Draw a horizontal line on the right side of your graph to represent the energy level of the products. This should be lower than the reactant energy level since the reaction is exothermic.
Remember, the main difference between the two graphs should be the height of the activation energy peak. The peak in the catalyzed reaction should be noticeably lower than the peak in the uncatalyzed reaction, representing the fact that a catalyst lowers the activation energy required for a reaction to occur.
