Question

For the reaction , $CO ( g) + H_2 O ( g) \rightleftharpoons \, CO_2 \, ( g) + H_2 \, ( g )$ 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)

Answer 1

Answer: (D)

increasing the amount of CO (g)

Answer 2

Adding reactant will drive the reaction in forward direction in order to restore equilibrium. Therefore, addition of CO (g) will increase the equilibrium amount of C$O_2$.
