Equilibrium Shift with Added Reactant

Hard General Chemistry Chemical Equilibrium

In a closed system, the reaction between nitrogen dioxide (NO₂) and dinitrogen tetroxide (N₂O₄) can be represented by the following equilibrium equation:

2 NO₂(g) <=> N₂O₄(g)

At a certain temperature, the equilibrium constant (K_c) for this reaction is measured to be 0.25. If 1.0 mole of NO₂ and 0.5 moles of N₂O₄ are placed in a 1-liter container at that temperature, what will be the direction of the shift in the equilibrium position when more NO₂ is added to the system?

The equilibrium will shift to the right, producing more N2O4.

The equilibrium will shift to the left, producing more NO2.

The equilibrium will remain unchanged.

The reaction will proceed to completion.
