Verified step by step guidance1
Examine the energy diagram provided. Notice the y-axis represents Free Energy and the x-axis represents the Progress of Reaction.
Identify the energy levels of the reactants and products. In this diagram, the reactants start at a lower energy level compared to the products.
Determine the change in free energy (ΔG) by comparing the energy level of the products to that of the reactants. Since the products are at a higher energy level than the reactants, ΔG is positive.
Recall that a positive ΔG indicates that the reaction requires an input of energy to proceed, which is characteristic of an endergonic reaction.
Conclude that the energy diagram represents an endergonic reaction, as the products have higher free energy than the reactants, indicating energy absorption during the reaction.
