Activation Energy

Name:
Activation Energy
Detailed information:
(1) Distinct energy states corresponding to minima of a potential energy surface in a configuration space. If tunneling is considered, lower energy paths become possible, but an activation energy can be associated with the reaction (at a given temperature) via the relationship between temperature and reaction rate. (2) The amount of energy (SI unit of joules) required to convert 1 mole of a reactant from the ground state to the transition state.
