Consider these hypothetical chemical reactions:

A⇌B,ΔG= 13.7 kJ/mol

B⇌C,ΔG= -27.2 kJ/mol

C⇌D,ΔG= 6.20 kJ/mol

What is the free energy, ΔG, for the overall reaction, A⇌D?

Express your answer with the appropriate units.
ΔG =

Firefly luciferase is the enzyme that allows fireflies to illuminate their abdomens. Because this light generation is an ATP-requiring reaction, firefly luciferase can be used to test for the presence of ATP. In this way, luciferase can test for the presence of life. The coupled reactions are

luciferin+O2ATP⇌⇌oxyluciferin+lightAMP+PPi

If the overall ΔG of the coupled reaction is -5.50 kJ/mol , what is the equilibrium constant, K, of the first reactions at 16 ∘C ? The ΔG for the hydrolysis of ATP to AMP is −31.6 kJ/mol.

Express your answer numerically.
