The Arrhenius theory and reaction coordinates relate to a particular perspective on chemical kinetics that imagines the path taken by the reactants as they are converted to the products. This change is not instantaneous and is typically slowed by the fact that in order to convert from reactants to products, the system must first pass through a higher energy state known as the transition state. The size of the energy barrier controls the temperature dependence of the rate constant. At any given temperature there is a distribution of energies for the molecules in the system. Some small fraction have enough energy to get over this barrier. The reaction rate then depends on the number of molecules that have sufficient energy. To speed up the rate, one can either raise the temperature or one can or lower the barrier. As a result, essentially all chemical reaction increase in rate as the temperature is increased. This is the idea that is the basis for the Arrhenius Law. However, this has...

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:

So let's look a little closer at the reaction coordinate diagram and what each point means: Let's start at 'A'. This is the reactants before the reaction has occurred. As the reaction occurs, energy is being added, and this energy is often in the form of heat. So, the line curves up until it reaches a peak. After this, the line curves down. In this example, 'B' (the products) is at a lower energy than 'A'. The amount of energy that had to be added is called the activation energy. And the difference in energy is called delta E, which is the difference in energy of the starting materials versus the finished product.
