# A mixture of \(\text{NO}(g)\) and \(\text{O}_2(g)\) is placed in a rigid container, as represented in the diagram below. The gases react to completion according to the following equation:

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

Which of the following particulate diagrams best represents the contents of the container after the reaction has gone to completion?

![A schematic representation of a gas mixture in a rectangular box. A legend in the upper corner maps: solid black circle = N atom, open white circle = O atom. Inside the box, there are exactly 6 NO molecules (each composed of 1 solid black circle touching 1 open white circle) and exactly 4 O2 molecules (each composed of 2 touching open white circles), randomly dispersed throughout the box. No other particles, labels, text, or annotations appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1787461365-blCaSc.jpg)
