    Exergonic: is a reaction where the change in the Gibbs free energy is negative, which indicates a spontaneous reaction
    -example: burning gas on a stove

    Endergonic: is a reaction where the change in the Gibbs free energy is positive, and the energy is absorbed.
    -example: dissolving salt in water

    We understood all aspects pretty well. =)

  2. To Jonathan and Jen,
    I am curious when you mentioned Gibbs free energy what kinds of concepts in your mind?
