Textbook problem 5G.9

[MelodyJiang]

Can someone explain why the ratio of Po2/Po3 will be different in the two containers at equilibrium?

[Aghigh Banitaba 1B]

Both of the systems are allowed to reach equilibrium and since they are just the reverse of each other, their K values will be inverse. Since K of the same reaction does not change, the ratio of the concentrations raised to their respective exponents will be the same but thee ratio of just the concentrations of the reactants and products will be different (since K is not calculated by just the concentration of reactants and products) To confirm this you can do the calculation but just remember that K of the first equation and so also the second must stay the same since you only are dealing with concentration. That makes figuring out the rest easier.
