For the gaseous reactions (I) and (II), the equilibriun constants are X and Y, respectively.
I.12N2 g+O2 g⇌NO2 g
II. 2NO2 g⇌N2O4 g
Using the above reactions the equilibrium constant Z for the reaction (III) given below is
III. N2O4 g⇌N2 g+2O2 g
  1. Z=XY
  2. Z=Y2X
  3. Z=1XY2
  4. Z=1X2Y

Solution

For the gaseous reactions (I) and (II), the equilibrium constants are X and Y, respectively.
I.12N2 g+O2 g⇌NO2 g.........(1)
II. 2NO2 g⇌N2O4 g.........(2)
 the equilibrium constant Z for the reaction (III)

III. N2O4 g⇌N2 g+2O2 g........(3)

Eq(3)=-{ Eq(1)×2 +Eq2}

Thus,Z=1X2Y.
