For the reaction
`CO(g)+H_(2)O(g) hArr CO_(2)(g)+H_(2)(g)`
at a given temperature, the equilibrium amount of `CO_(2)(g)` can be increased by

A

Adding a suitable catalyst

B

Adding an inert gas

C

Decreasing the volume of the container

D

Increasing the amount of `CO(g)`

Text Solution

Verified by Experts

The correct Answer is:
D
`CO(g)+H_(2)O(g) hArr CO_(2)(g)+H_(2)(g)`
At constant volume, there is no effect of addition of inert gas to a reaction in equilibrium.
At constant pressure, for the reactions for which `Deltan=0`, there is no effect of addition of inert gas to a reaction in equilibrium. The presence of a catalyst just helps to achieve the equilibrium at a different pace. It does not affect the amount of a reactant or a product at equilibrium.
Only if the reactant concentration is increased, the equilibrium shifts forward and the product concentration in increased.
