The equilibrium constant for the reaction A ‡Œ B is Kc = 10 at a certain temperature.
(1) Starting with only reactant A, which of the diagrams shown here best represents the system at equilibrium?
(2) Which of the diagrams best represents the system at equilibrium if Kc = 0.10? Explain why you can calculate Kc in each case without knowing the volume of the container. The gray spheres represent the A molecules and the green spheres represent the B molecules.
