If you observe the following reaction at equilibrium, is it possible to tell whether the reaction started with pure NO2 or with pure N2O4? Also, write the Kc and Kp expressions for this equilibrium and determine the appropriate units: 2 NO2(g) ⇌ N2O4(g) If Kc = 5.6 x 10-8 M-1 (are the units correct?), what does this mean with respect to the amount of reactant and product? What if, at a different T, Kc = 3.1 x 102 M-1?
