Energy Of Activation (Noun)
Meaning
The energy that an atomic system must acquire before a process (such as an emission or reaction) can occur; "catalysts are said to reduce the energy of activation during the transition phase of a reaction".
Classification
Nouns denoting natural phenomena.
Examples
- The enzyme lowers the energy of activation required for the biochemical reaction to proceed.
- Catalysts are substances that reduce the energy of activation needed for a chemical reaction.
- At higher temperatures the energy of activation for the reaction is reached more frequently.
- The energy of activation for a spontaneous reaction may be relatively high or low.
- Lowering the energy of activation allows the reaction to take place with a lower input of energy.
