Consider the reaction between NO and Cl2 to form NOCl:
2NO(g)+Cl2(g)â2NOCl(g)
A reaction mixture at a certain temperature initially contains only [NO]= 0.68 M and [Cl2]= 0.57. After the reaction comes to equilibrium, the concentration of NOCl is 0.23 M .

Find the value of the equilibrium constant (Kc) at this temperature.
