Calculating equililbrium composition from an equilibrium constant Suppose a 500. mL flask is filled with 1.4 mol of N2 and 1.8 mol of NO. The following reaction becomes possible: N2(g) + O2(g) 2NO(g) The equilibrium constant K for this reaction is 5.68 at the temperature of the flask. Calculate the equilibrium molarity of NO. Round your answer to two decimal places.
