Consider the following equilibrium:
Initially, 0.600 mol of NO2 is placed in a 1.00 L flask. At equilibrium, the concentration of NO was found to be 0.460 mol/L.
The equilibrium law expression would be

From this information it can be inferred that the system
is at equilibrium.
is not at equilibrium and the system needs to move in the reverse direction to reach equilibrium.
is not at equilibrium and the system needs to move in the forward direction to reach equilibrium.
is not at equilibrium but no further analysis can be done without knowing the initial concentrations.
