1. 1) luciferin+O2 ⇌ oxyluciferin+light

2) ATP⇌AMP+PPi ΔG∘=−31.6 kJ/mol

If the overall ΔG∘ of the coupled reaction is -1.21 kJ/mol , what is the equilibrium constant, K, of the first reaction at 11∘C? Round your answer to 3 significant figures.

2. When methanol (CH3OH) is combusted, such as when in a gasoline blend, the following reaction occurs:

2CH3OH(l)+3O2(g)→2CO2(g)+4H2O(g)

Based on the standard free energies of formation given, what is the standard free energy change for this reaction? Report the answer in kJ/mol rxn rounded to the ones place.

    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.
