• The part that represents the ativation energy is ,from the top of the hill to the dotted line., indicated by, activation energy arrow.

,

• and the part that represents ,a change when a catalyst, id added is the dotted curve line below the activation energy dome, indicated by ,activation energy with a catalyst,.Catalysts decrease the activation energy required
