Activation energies for the second steps of both mechanisms are the same, 20 kJ. Homogeneous Catalysts A homogeneous catalyst is present in the same phase as the reactants. energy diagram catalyzed vs uncatalyzed reaction The energy diagram for a uncatalyzed reaction is an alternative way to describe a reaction. It's just a graph that shows the concentration of the reactant as well as the product. If your reaction isn't catalyzed, then the energy diagram will show this, meaning that the reaction has an exothermic reaction.

Diels–Alder reaction - Wikipedia The "prevailing opinion" is that most Diels–Alder reactions proceed through a concerted mechanism; the issue, however, has been thoroughly contested. Despite the fact that the vast majority of Diels–Alder reactions exhibit stereospecific, syn addition of the two components, a diradical intermediate has been postulated (and supported with computational evidence) on the grounds that the ...
