The diagram above shows the free energy G for several possible
states (gray lines) of a chemical reaction. The black arrows
represent possible transitions between these states, and the
brackets represent the corresponding free energy differences.
Consider the meaning of the different terms in the relation:
?G = ?G°' + RTlnQ
Select the option which most closely corresponds to each
description.
