Question

Under standard conditions, a given reaction is endergonic (i.e., DG >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?

using the product immediately in the next step maintaining a high starting-material concentration keeping a high product concentration using the product immediately in the next step and maintaining a high starting-material concentration

Explanation / Answer

In a endergonic reaction free energy change is positive & energy is absorbed.

K=e^-delta G^o/ RT

K<1 since delta G^o is +ve.so such a reaction would move backwards toward equilibrium.

this reaction favorable: using the product immediately in the next step and maintaining a high starting-material concentration
