Nitrogen monoxide gas, \(\text{NO(g)}\), reacts with oxygen gas, \(\text{O}_2\text{(g)}\), to form nitrogen dioxide gas, \(\text{NO}_2\text{(g)}\), according to the following balanced equation:

\[ 2\text{NO(g)} + \text{O}_2\text{(g)} \rightarrow 2\text{NO}_2\text{(g)} \]

A particulate representation of a mixture of \(\text{NO(g)}\) and \(\text{O}_2\text{(g)}\) in a rigid vessel prior to reaction is shown in the diagram. Assuming the reaction proceeds to completion, which of the following particulate diagrams best represents the contents of the vessel after the reaction has finished?
