Detailed explanation-1: -Reactions with a positive ∆G (∆G > 0), on the other hand, require an input of energy and are called endergonic reactions. In this case, the products, or final state, have more free energy than the reactants, or initial state.
Detailed explanation-2: -Endergonic reactions have a positive ∆G and exergonic reactions have a negative ∆G. Endergonic reactions consume energy and exergonic reactions release energy. Both endergonic and exergonic reactions require a small amount of energy to overcome an activation barrier.
Detailed explanation-3: -An endergonic reaction has a positive (greater than zero) change in Gibbs free energy (G). This decreases entropy (S). Endergonic reactions do not occur spontaneously.
Detailed explanation-4: -Endergonic reactions require an input of energy; the ∆G for that reaction will be a positive value. Exergonic reactions release free energy; the ∆G for that reaction will be a negative value.
Detailed explanation-5: -Endergonic reactions are nonspontaneous. The progress of the reaction is shown by the line. The change of Gibbs free energy (
