A student investigates the gas-phase reaction at a constant temperature of \(298\text{ K}\):

\[ 2\,\text{NO}_2\text{(g)} \rightleftharpoons \text{N}_2\text{O}_4\text{(g)} \]

Four separate sealed, rigid \(1.0\text{ L}\) containers are prepared with different amounts of \(\text{NO}_2\text{(g)}\) and \(\text{N}_2\text{O}_4\text{(g)}\). The concentrations of the gases in each container are measured after a period of time, as shown in the table below.

Mixture	\([\text{NO}_2]\text{ (M)}\)	\([\text{N}_2\text{O}_4]\text{ (M)}\)
1	\(0.020\)	\(0.040\)
2	\(0.050\)	\(0.25\)
3	\(0.10\)	\(1.0\)
4	\(0.040\)	\(0.32\)

Which of the following correctly identifies the mixture that is not at equilibrium and the direction in which the net reaction will proceed to establish equilibrium?
