Problem

Nitrogen tetroxide and nitrogen dioxide form an equilibrium mixture according to the equation N2_2O4_4(g) ⇌ 2 NO2_2(g) A 2.00 L rigid container at 298 K is initially filled with 2.000 mol of pure N2_2O4_4(g). After the system comes to equilibrium at the same temperature, 0.580 mol of N2_2O4_4 remain. (a) Calculate the equilibrium molar concentration of each gaseous species present in the container. (b) Determine the value of KcK_c for the reaction at 298 K. Report your answer with the correct number of significant figures and units. (c) Using the value of KcK_c from part (b), calculate KpK_p for this reaction at 298 K.
