In an energy diagram, the vertical axis represents the overall energy of the reactants, while the horizontal axis is the 'reaction coordinate', tracing from left to right the progress of the reaction from starting compounds to final products. The energy diagram for a typical one-step reaction might look like this:

The diagram below is called a reaction coordinate diagram. It shows how the energy of the system changes during a chemical reaction. In this example, B is at a lower total energy than A. This is an exothermic reaction(heat is given off) and should be favorable from an energy standpoint. The energy difference between A and B is E in the diagram.

SN2 reaction coordinate diagram. In this diagram, there are really only three parts: the reagents, the transition state, and the products. The transition state is the point in the reaction with the highest energy level, and the difference in energy between the reagents and transition state is called the activation energy (often abbreviated as Ea).

Typically, we envision reactions proceeding left to right along the reaction coordinate, so often, the activation energy is only noted for the forward reaction. The activation energy on the diagram below shows the barrier to be 102.6 kJ mol -1. Barriers are measured in energy per mole (typically kJ mol -1 ). Arrhenius Law and Temperature Dependence
