Problem: For the reaction N2O4(g) ⇌ 2 NO2(g), a reaction mixture at a certain temperature initially contains both N2O4 and NO2 in their standard states. If Kp = 0.15, which statement is true of the reaction mixture before any reaction occurs?(a) Q = K; the reaction is at equilibrium.(b) Q < K; the reaction will proceed to the right.(c) Q > K; the reaction will proceed to the left.
