Chemical Equilibrium

Q. At 200 degrees C the equilibrium constant, Kc, = 1.4x10^-10 for the rection: N2O (g) + NO2 (g) --> 3 NO (g). When 7.90 g of N2O and 16.60 g of NO2 are placed in a 0.40 liter container the equilibrium is established. a. What is the equilibrium concentration of the NO? b. What is the value of the Kp for this reaction?
