At a given temperature, 0.300 mole NO, 0.200 mol Cl2 and 0.500 mol ClNO were placed in a 25.0 Liter container. The following equilibrium is established:
2ClNO(g) 2NO(g) + Cl2(g)
At equilibrium, 0.600 mol of ClNO was present. What are the number of moles of Cl2 present at equilibrium? and what is the equilibrium constant, Kc?
