The difference between F1F1F1S1F1F1F10H° and F1F1F1S1F1F1F10E° is determined by the change in entropy (ΔS) and Gibbs free energy (ΔG) of the reaction. In general, reactions with more reactants and fewer products tend to have a larger difference between ΔH° and ΔG°. Option D has the most reactants (9) and the fewest products (10), which suggests a large difference between ΔH° and ΔG°. Therefore, option D is the best choice.
