Question: 2 NO 2 ( g ) N 2 O 4 ( g ) dark brown colorless The dimerization of NO 2 ( g ) ,
2 NO2(g) N2O4(g)
dark brown colorless
The dimerization of NO2(g) , an exothermic process, is represented by the equation above.
A 0.0688 mol sample of NO2(g) is placed in a rigid 1.00 L reaction vessel and allowed to reach equilibrium at a certain temperature. What is the value of Kc at this temperature if 0.0133 mol of N2O4(g) is present at equilibrium?

he dimerization of NO2(g), an exothermic process, is represented by the equation above. (A) 0.134 (B) 0.315 (C) 4.32 (D) 7.47
