Sketch a qualitative reaction energy diagram for a chemical reaction with and without a catalyst. Assume the uncatalyzed reaction is endothermic.
Note: Because the sketches are only qualitative, the energies in them don't have to be exact. They only have to have the right relationship to each other. For example, if one energy is less than another, that fact should be clear in your sketch.
