what is activation energy. |
|
Answer» Activation energy, inchemistry, the minimum amount of energy that is required to activateatomsormoleculesto a condition in which they can undergo chemical transformation or physical transport. Intransition-state theory, the activation energy is the difference in energy content between atoms or molecules in an activated or transition-state configuration and the corresponding atoms and molecules in their initial configuration. The activation energy is usually represented by the symbolEain mathematical expressions for such quantities as thereaction rateconstant,k=Aexp(−Ea/RT), and thediffusioncoefficient,D=Doexp(−Ea/RT) |
