\[ \text{A}_2\text{(g)} + \text{B}_2\text{(g)} \rightleftharpoons 2\,\text{AB(g)} \]

A reversible gas-phase reaction is represented by the equation above. In Experiment 1, a rigid \(1.0\text{ L}\) container at a constant temperature of \(500\text{ K}\) contains an equilibrium mixture consisting of \(2\) molecules of \(\text{A}_2\), \(2\) molecules of \(\text{B}_2\), and \(4\) molecules of \(\text{AB}\), as shown in the diagram below (where each particle represents \(0.10\text{ mol}\) of gas).

In Experiment 2, a second identical \(1.0\text{ L}\) rigid container at the same temperature of \(500\text{ K}\) is initially filled with \(6\) molecules of \(\text{A}_2\) and \(6\) molecules of \(\text{B}_2\) (\(0.60\text{ mol}\) of each gas) and allowed to reach equilibrium.

Which of the following particulate diagrams best represents the equilibrium mixture in Experiment 2?
