The reversible reaction is,
    Â
Applying the law of chemical equilibrium
          Â
Putting the values, we have,
     Â
 Â
The value of Kc for the reaction  is  at  If the equilibrium concentration of  in air at  is  what is the concentration of O3?vÂ
Calculate the value of equilibrium constant for the reaction:
There is 10.0 mol of N2, 14·0 mol of O2 and 0·2 mol of NO2 present at equilibrium in a 3·0L vessel at 298K.What will be the effect of increased temperature on the equilibrium constant?
