Energy Diagrams of Reactions | Fiveable To find the activation energy, you should be looking for two numbers: the potential energy of the reactants and the energy of the activated complex (the maximum point). (energy of activation complex) - (PEreactants) (100 kJ) - (40 kJ) = 60 kJ In other words, it takes 60 kJ of energy to complete the reaction. Multistep reaction energy profiles (video) - Khan Academy Next, let's look at the energy profile for this multi-step reaction. Energy profiles usually have potential energy in the y-axis and then reaction progress on the x-axis. So as we move to the right on the x-axis, the reaction is occurring. This first line on our energy profile represents the energy level of our reactants, which are BC and D. 7.4 SN1 Reaction Mechanisms, Energy Diagram and Stereochemistry S N 1 is a multiple-step reaction so the diagram has multiple curves, and each step can be represented by one curve. Out of the three steps, the activation energy for step 1 is the highest; therefore, step 1 is the slowest step, which is the rate-determining step. Figure 7.4a Energy diagram for SN1 reaction between (CH3)3CBr and H2O 12.7 Catalysis - Chemistry - opentextbc.ca This potential energy diagram shows the effect of a catalyst on the activation energy. The catalyst provides a different reaction path with a lower activation energy.

Multistep Reactions - Softschools.com The energy diagram of a two-step reaction is shown below. In the above reaction, a reactant goes through one elementary step with a lower activation energy (transition state 1) to form the intermediate. The intermediate then goes through a second step (transition state 2) with the highest energy barrier to form the product.
