A(n) _____ Requires an Input of Energy to Proceed

Question

A(n) _____ requires an input of energy to proceed.
A) reaction at equilibrium
B) irreversible reaction
C) spontaneous reaction
D) exergonic reaction
E) endergonic reaction

Accepted Answer

Endergonic reactions require an input of energy to proceed, as they have a positive Gibbs free energy change ($\Delta G > 0$), indicating that the products have more free energy than the reactants.
