- Which one of the following statements is completely TRUE? O When AG > 0, the reaction is BOTH product-favored (spontaneous) AND endergonic. When AG 0, the reaction is BOTH reactant-favored (nonspontaneous) AND endergonic. When AG > 0, the reaction is BOTH product-favored (spontaneous) AND exergonic. When AG > 0, the reaction is BOTH reactant-favored (nonspontaneous) AND exergonic.
