Question

What happens when an inert gas is added to an equilibrium keeping volume unchanged ? (A) More product will form (B) Less product will form (C) More reactant will form (D) Equilibrium will remain unchanged

Tardigrade Admin · Accepted Answer

On adding inert gas at constant volume the total pressure of the system is increased, but the partial pressure of each reactant and product remains the same. Hence no effect on the state of equilibrium.

Less product will form

More reactant will form

Equilibrium will remain unchanged
