In nature, one common strategy to make thermodynamically unfavorable reactions proceed is to couple them chemically to reactions
maks197457 [2]

Answer:

31.3 kJ/mol is the free energy, ΔG, for the overall reaction, A⇌D.

Explanation:

A⇌B, \Delta G_1 = 11.9 kJ/mol  ...[1]

B⇌C, \Delta G_2= -26.7 kJ/mol  ...[2]

C⇌D, \Delta G_3= 7.30 kJ/mol  ...[3]

A⇌D, \Delta G_4 = ?...[4]

[4] = [1] - [2] - [3]  (Using Hess's law)

\Delta G_4=\Delta G_1-(\Delta G_2+\Delta G_3)

=11.9 kJ/mol - (-26.7 kJ/mol+7.30 kJ/mol)

=\Delta G_4=31.3 kJ/mol

31.3 kJ/mol is the free energy, ΔG, for the overall reaction, A⇌D.
