Question

Why does the addition of an inert gas to a constant-volume equilibrium mixture of gases not disturb the equilibrium?.

Answer 1

Uhhhh I think this is it

Step-by-step explanation:

Some changes to total pressure, like adding an inert gas that is not part of the equilibrium, will change the total pressure but not the partial pressures of the gases in the equilibrium constant expression. Thus, addition of a gas not involved in the equilibrium will not perturb the equilibrium.
