Quizplus · Accepted Answer

The △G for a reaction is the difference between the free energy of the products and the free energy of the reactants. In this case, the free energy of the products (C and D) is lower than the free energy of the reactants (A and B), so the △G is negative. Based on the figure, option D represents a negative △G, indicating that the reaction is spontaneous.
