It would be exergonic because it's reaction is a chemical reaction where the change in the free energy is negative (there is a net release of free energy), indicating a spontaneous reaction. These reactions usually do not require energy to proceed, and therefore it would occur spontaneously.
The correct answer: Exergonic.
Exergonic is the form of chemical reaction in which the changes over the free energy is much negative. There is the composition of the net release over the free energy. They are such kind of reactions that does not need any sort of energy.
