For the reaction : CO ( g ) + H 2 ​ O ( g ) ⇌ CO 2 ​ ( g ) + H 2 ​ ( g ) at a given temperature, the equilibrium amount of CO 2 ​ ( g ) can be increased by :

TestHub · Accepted Answer

The correct options are (B) and (D) based on Le Chatelier's principle.

Removing H₂(g): Shifts equilibrium forward to replace lost product, increasing CO₂.

Increasing CO(g): Shifts equilibrium forward to consume extra reactant, producing more CO₂.

Volume change: Has no effect because total gas moles are equal on both sides ( $Δ n_{g} = 0$ ).

Catalyst: Only speeds up the reaction rate without changing the final equilibrium amounts.
