activation energy

Definitions

from Wiktionary, Creative Commons Attribution/Share-Alike License

  • n. The energy required to initiate a reaction. For example, the flame from the fuse of a firecracker provides a small initial amount of energy, after which the explosive reaction proceeds by itself, releasing a considerably larger quantity of energy. A small push given to a stable but top-heavy object may cause it to fall over; the potential energy released during the fall was present in the system all along but could not be realized as long as the object was upright and balanced.

  • n. the energy that an atomic system must acquire before a process (such as an emission or reaction) can occur
