What concentration of Cl2O remains after a mixture that initially contains [H2O] = 1.00 M and [Cl2O] = 1.00 M comes to equilibrium at 25 °C ? Kc for the reaction is 0.0900.

Equilibrium concentration of   is 0.870 M.

Explanation:

Initial concentration of water =

Initial concentration of

initially

1.00 M            1.00 M                      0

At equilibrium

(1.00m-x) M   (1.00-x)M                  2x

The expression of equilibrium constant is given by :

Solving for x :

x = 0.130

Equilibrium concentration of  :
