At a certain temperature, Kc = 1.55 for the reaction NO 2(g) + NO(g) <==> N 2O(g) + O2(g) At the same temperature is prepared a mixture containing 0.30 mol NO 2, 0.30 mol NO, 0.35 mol N 2O, and 0.35 mol O 2 in a 4.00 L container and is allowed to reach the equilibrium. What will be the equilibrium concentration of O2 ?
