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) A. No, Q = 0.18 so the reaction should proceed in the forward direction. B. No, Q = 9.0 × 10^-2 so the reaction should proceed in the reverse direction. C. Yes, the reaction is at equilibrium. D. No, Q = 4.5 ×10^-2 so the reaction should proceed in the reverse direction.

    Why don't you focus more on trying to answer this question yourself instead of trying to establish a singing contest in the math chat. There are books which can help you with this:
