Answer
(a) > (b) > (c)
Work Step by Step
Since the reaction is the same in all of the concentrations, the equation for the equilibrium constant will also be the same, so it depends on the concentration. If you divide the number of molecules of product dived by the number of reactants, the equilibrium constant is 2 for (a). If you divide the number of molecules of product dived by the number of reactants, the equilibrium constant is 0.375 for (b). If you divide the number of molecules of product dived by the number of reactants, the equilibrium constant is 0.0612 for c. If you rank these equilibrium constants, you get (a) > (b) > (c)
