15 In the chemical reaction where N2O4(g) is converted to 2NO2(g), if 0.5 M N2O4 and 0.15 M NO2 are present in the vessel, is the reaction at equilibrium? If not, which direction would the reaction proceed? (Kc = 4.4 × 10-3) N2O4(g) 2NO2(g)

No, Q = 9.0 × 10-2 so the reaction should proceed in the reverse direction.


No, Q = 0.18 so the reaction should proceed in the forward direction.


No, Q = 4.5 ×10-2 so the reaction should proceed in the reverse direction.


Yes, the reaction is at equilibrium.
