Delta G

Postby Raquel Ruiz 1K » Sun Feb 17, 2019 8:40 pm

Can someone clarify what exergonic and endergonic mean ? And how they relate to delta G. Thanks!

Exergonic is when delta G is negative.
Endergonic is when delta G is positive.

Exergonic: (-) sign. It releases energy spontaneously, which fits our definition for a negative delta G value. The bonds formed are essentially stronger than the bonds broken.

Endergonic: (+) sign. It absorbs energy, which fits the definition of the positive delta G value, being not spontaneous at all. The bonds formed are essentially weaker than the bonds broken.

Exergonic processes release energy. The change in Gibbs free energy (ΔG) is a negative value because energy is lost,
whereas an endergonic processes absorbs energy and their products are of greater free energy than the reactants.
