Energy barriers and rate equations
Energy barriers and rate equations
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}}Ea is the minimum energy needed for a successful collision.
