Recall that an energy diagram is usually read from left to right


The components of a two-step energy diagram are:



• Reactants: are placed on the left/beginning of the energy diagram

• Products: are placed on the right/end of the energy diagram

• Non-limiting transition state: is the transition state with the lowest energy in the energy diagram

• Rate-limiting transition state: is the transition state with the highest energy in the energy diagram

• Intermediates: are formed in between steps in the energy diagram

• Energy change (ΔH or ΔG˚): is the difference in energy between products and reactants

• Activation energy (Ea): is the difference in energy between reactants and transition state


Below is an example of a labelled diagram:
