For problem 11.3 in the textbook, how can you determine that it is Flask 3 that is at equilibrium without any value of K?

The problem asks us to see when the rate of decomposition of the X2 molecules has reached equilibrium. In Flask 1 and 2, the X2 molecules continue to dissociate into X molecules. In Flask 3, about half of the X2 molecules have dissociated. Since the number of X2 molecules and X molecules don't change from Flask 3 to Flask 4, you can deduce that the rate that the X2 changes to X and vice versa are the same. This means that the reaction reaches equilibrium at Flask 3.
