Three gaseous reactions are carried out at 298\,K under standard-state conditions. Standard molar free-energy changes are given below.
(a) List the three reactions in order of decreasing equilibrium constant K (largest K first).
(b) Provide a concise justification for your ranking that references both the sign and the magnitude of the given ΔG∘ values.
(c) Identify which reaction’s equilibrium lies farthest toward reactants and explain how the numerical value of ΔG∘ supports that conclusion.
