Hint: An exergonic reaction is a chemical reaction where their release of free energy and an endergonic reaction is a chemical reaction where energy is absorbed.
Complete answer: An exergonic reaction is a type of spontaneous reaction where there is ‘release ' of free, here free energy is negative (less than zero).
On the contrary, endergonic reactions are the reactions where energy enters the system, the free energy here is positive (greater than 0).
Free energy or Gibbs free energy (∆G) is nothing but the total available energy. If free energy is negative (-∆G), it means that energy is released and if it is positive, the energy is being absorbed/stored.
Note: Endergonic and exergonic reactions form the basis of the reactions happening in various organisms.
Catalysts may be required for some reactions to proceed at an observable speed.

Exergonic reaction | Endergonic reaction |
The exergonic reaction is a type of reaction in which free energy is released | Endergonic reactions are the type of reaction in which free energy is absorbed. |
Here Gibbs free energy is negative | Here Gibbs free energy is positive |
Exergonic reactions indicate that the energy is released in the system | Endergonic reactions indicate that the energy is absorbed by the system. |
All the exothermic reactions are exergonic. | All endothermic reactions are endothermic. |
Exergonic reactions do not require energy to begin | Endothermic reactions always require energy to begin. |
It is a downhill reaction. | It is an uphill reaction |
