What would be the net ∆G′ for the coupling of these two reactions?

Question

Quizplus · Accepted Answer

To calculate the net ∆G′ for the coupling of these two reactions, we add the ∆G′ values of the two reactions together. ∆G′ = ∆G′₁ + ∆G′₂ = (-5.737) + (-2.722) = -8.459 kcal/mol. However, since the second reaction is being reversed, we change the sign of the ∆G′ value. Therefore, the net ∆G′ for the coupling of these two reactions is +3.459 kcal/mol (the opposite sign of -3.459 kcal/mol), which is option D.
