In reaction A, the stability of the substrate is less than the stability of the product. The free energy change, ΔG, of the reaction is negative, so the reaction is considered exergonic and spontaneous. In reaction B, the stability of the substrate is greater than the stability of the product. The free energy change, ΔG, of the reaction is positive, so the reaction is considered endergonic and not spontaneous.
