Under standard conditions, a given reaction is endergonic (i.e., ΔG >0). Which of the following can render this reaction favorable: using the product immediately in the next step, maintaining a high starting-material concentration, or keeping a high product concentration?a. using the product immediately in the next step
b. maintaining a high starting-material concentration
c. keeping a high product concentration
d. using the product immediately in the next step and maintaining a high starting-material concentration

An endergonic reaction requires input of energy to drive the reaction since it is not spontaneous. Using the product in the next step drives the equilibrium towards producing more products in accordance with LeChateliers principle. The immediate use of products drives the forward reaction hence the reaction continues to progress in the forward direction.
