Consider the following equilibrium system:

2NO(g)+Cl2(g)?2NOCl(g) Kc=4.7×103

A sample mixture is tested and it is determined to contain all three entities in the following concentrations:

2NO(g)=0.53 mol/L

Cl2(g)=0.11 mol/L

2NOCl(g)=0.021 mol/L

From this information it can be inferred that the system

Select one:
is not at equilibrium but no further analysis can be done without knowing the initial concentrations.
is not at equilibrium and the system needs to move in the reverse direction to reach equilibrium.
is at equilibrium.
is not at equilibrium and the system needs to move in the forward direction to reach equilibrium.
