2.50 mol NOCl was placed in a 2.50 L reaction vessel at 400ºC. After equilibrium was established, it was found that 28.0% of the NOCl had dissociated according to the equation 2NOCl(g)  <--> 2NO(g) + Cl2(g). Calculate the equilibrium constant, Kc, for the reaction. (3 sig figs) ( ICE table with all numbers, no unknown  x)
