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.
