Imagine the reaction A → B with a negative ΔG value under experimental conditions. Which of the following statements is true about this reaction?

A) The reaction is energetically unfavorable.
B) The reaction proceeds spontaneously and rapidly under these conditions.
C) Increasing the concentration of B molecules would increase the ΔG value (toward more positive values).
D) The reaction would result in a net decrease in the entropy (disorder) of the universe.
E) The reaction cannot proceed unless it is coupled to another reaction with a positive value of ΔG.
