Answer:
Ionic Exergonic
Explanation:
Exergonic reactions have negative Gibbs free energy and hence are spontaneous.
Endergonic reactions have negative Gibbs free energy and are non-spontaneous and low temperature.
Endergonic reactions require external supply of energy. But such reactions can be made spontaneous or favorable by coupling with exergonic reaction via a common intermediate.
Therefore, the correct answer is Ionic Exergonic.
