The gas-phase reaction A(g) ⇌ B(g) reaches equilibrium at the same temperature in four identical 1.0 L containers. Each circle represents one molecule.
• Container W: 48 A and 2 B
• Container X: 30 A and 20 B
• Container Y: 20 A and 30 B
• Container Z: 5 A and 45 B
Which container is most consistent with an equilibrium constant K that is much greater than 1 at this temperature?
a) Y
b) W
c) Z
d) X
