One mole of NOCl gas is added to a 4.0L container. the NOCl undergoes slight decomposition to form NO gas and Cl2 gas. If the equilibrium constant, Kc, for the rxn 2NOCl(g)--->2NO(g)+Cl2(g) is 2.0x10^-10 @ 25 degrees celsius, calculate the concentration of all the species at equilibrium at this temperature
