For the reaction, 
, 
and 
Which of the following statements is correct?
(I) The equilibrium will shift in forward direction as the pressure increases.
(II) The addition of inert gas at constant volume will not affect the equilibrium constant.
(III) The equilibrium constant is large suggestive of reaction going to completion and so no catalyst is required.
(IV) The equilibrium constant decreases as the temperature increases.
(V) The equilibrium will shift in backward direction as the pressure increases.
Choose the correct option.
Text Solution
Verified by ExpertsB
Among the given statements I, II and IV are correct while III and V are incorrect. The larger value of 
suggest that the reaction should go almost to completion. However, practically, the oxidation of 
to 
is very slow. Hence, the rate of reaction is increased by adding catalyst. Also, the equilibrium will shift in forward direction as the pressure increases.
