$226.$ In a reversible chemical reaction $($where$,$ x $=$ number of moles of products$-$number of moles of reactants$)$

Addition of inert gas favours the forward reaction, when x is positive

Pressure has no effect on equilibrium, when n $=0$

Addition of inert gas has no effect on the equilibrium constant at constant volume for any value of x $(+$ ve$,-$ ve$)$ or zero$)$
