Understanding potential and kinetic energy in action
potential energy landscape potential energy potential energy as a function of elongation of a fissioning nucleus Potential-energy curve. The activation energy represents the minimum amount of energy required to transform reactants into products in a chemical reaction. The value of the activation energy is equivalent to the difference in potential energy between particles in an intermediate configuration (known as the transition state, or activated complex) and particles of reactants in their initial state. The activation energy thus can be visualized as a barrier that must be overcome by reactants before products can be formed.
