Energy Diagram - Organic Chemistry Video | Clutch Prep This just happened to be negative 436 kilojoules per mole. You don't need to memorize that at all. Later on, we're going to use a chart to figure that out. But what is important is that all this information can be related on the free-energy diagram. So the free-energy diagram is basically a storyline of everything that I just said. 8.2. Physical chemistry for SN2 and SN1 reactions ... A potential energy diagram for an S N 1 reaction shows that the carbocation intermediate can be visualized as a kind of "mountain valley" in the path of the reaction, higher in energy than both the reactant and product but lower in energy than the two transition states.
