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

Options

A. adding a suitable catalyst
B. adding an inert gas
C. decreasing the volume of the container
D. increasing the amount of CO (g)

Answer

D

Explanation

Catalyst has no effect on equilibrium . Decreasing the volume or pressure has no effect because `n_(r)=n_(p)`. Therefoer , the equilibrium shifts in the forward direction by increasing the conc. Of reatant CO (g).
