For the chemical system CO + Cl2 COCl2; K = 4.6 x 109. If the concentration of the product were to double, what would happen to the equilibrium constant?
It would double its valueIt would become half its current value.It would quadruple its valueIt would not change its value.It would depend on the initial conditions of the product.
