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

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