Problem
The reversible reaction A(g) ⇌ B(g) is at equilibrium in three identical containers at the same temperature. A particle-level snapshot of each container shows the following counts:
• Container I: 5 molecules of A and 15 molecules of B
• Container II: 7 molecules of A and 14 molecules of B
• Container III: 12 molecules of A and 8 molecules of B
Rank the three containers from largest to smallest equilibrium constant K for the reaction and give a one-sentence justification for your ranking.
