Solution :
Mass action ratio (Q) :
The mass-action ratio is the ratio of product concentrations to reactant concentrations at the given time whether reaction is in equilibrium or not.
Q = [Concentration of product /Concentration of reactant]
Standard free energy changes are additive because change in standard free energy of reaction,
ΔG°rxn = ΔG° product - ΔG° reactant
