endergonic
(adjective)
Describing a reaction that absorbs energy from its surroundings.
Examples of endergonic in the following topics:
-
Spontaneous and Nonspontaneous Processes
- An endergonic reaction (also called a nonspontaneous reaction or an unfavorable reaction) is a chemical reaction in which the standard change in free energy is positive, and energy is absorbed.
- Endergonic reactions can also be pushed by coupling them to another reaction, which is strongly exergonic, through a shared intermediate.Saul Steinberg from The New Yorker illustrates a nonspontaneous process here.
-
Solvent Effects
- These different entropy changes are incorporated in the free energy of solution, which is exergonic for NaCl, but endergonic for CaF2.
