Energy barriers and rate equations

Reaction profile for an exothermic reaction with reactants, products, transition state, activation energy and enthalpy change labelled Reaction mechanisms explain what happens in the tiny steps between reactants and products. A collision only leads to reaction if particles have the correct orientation and enough energy to reach the transition state, so the activation energy $EaE_{\text{a}}$ is the minimum energy needed for a successful collision.
