Problem
Each of the following containers holds a different gas-phase reaction at equilibrium and all containers have the same volume and temperature.
• Reaction 1: A₂(g) ⇌ 2 A(g) Snapshot: 12 A atoms and 3 A₂ molecules
• Reaction 2: B₂(g) ⇌ 2 B(g) Snapshot: 8 B atoms and 16 B₂ molecules
• Reaction 3: C₂(g) ⇌ 2 C(g) Snapshot: 10 C atoms and 4 C₂ molecules
Rank the three reactions from largest to smallest equilibrium constant K, showing your reasoning in no more than two sentences.
