- Reaction without catalyst
---- Reaction with catalyst
The graph shows the reaction progression for an
endothermic reaction with a catalyst. What is
indicated by the fact that the red curve does not
go as high up as the black curve?
The amount of energy released by the
reaction is higher with the catalyst present
than it is without it.

Intro

Answer 1

Answer: The reaction has a lower activation energy with the catalyst present than it has without it.

Explanation:

If you project both curves on the Y axis, which represents the amount of energy required for activating the reaction, you can see that the red curve has a lower value than the black curve. This makes perfect sense, since the purpose of a catalyst is of lowering the energy required for activating a reaction.
