Calculate the changes in the CO and Cl2 concentrations that occur if the concentration of COCl2 decreases by 0.103 mol/L as the following reaction comes to equilibrium.

The CO concentration decreases or increases by mol/L.

The Cl2 concentration increases or decreases by mol/L.

B)Which of the following equations describes the relationship between the magnitude of the changes in the NO2 and O2 concentrations as the following reaction comes to equilibrium?

(NO2) = (O2)

2 (NO2) = (O2)

(NO2) = 2 (O2)
