Chemical Engineering Thermodynamics
In a reversible chemical reaction (where, Δx = number of moles of products-number of moles of reactants )

Pressure has no effect on equilibrium, when Δn = 0
Addition of inert gas favours the forward reaction, when Δx is positive
Addition of inert gas has no effect on the equilibrium constant at constant volume for any value of Δx (+ ve, - ve) or zero)
All of these
