### Catalysts in relation to Graph Peaks

I know that larger peaks mean that more activation energy is required for the reaction. But does this also mean that higher peaks are more likely to have catalysts present? Are there any defining features on the graph that reveal the use of a catalyst?

When a catalyst is present, there is a lower activation energy because the reaction is sped up.

In an reaction profile diagram, the presence of a catalyst is typically indicated by the addition of a dotted line of the lower activation energy barrier. The original Ea peak should still be drawn.
