For a given equilibrium reaction, addition of inert argon gas at constant volume can shift the equilibrium in $\mathrm{N}_2(g)+3 \mathrm{H}_2(g) ightleftharpoons 2 \mathrm{NH}_3(g)$
forward direction
backward direction
remain unaffected
initially forward and then backward direction
Solution
The expression to $K_p$ of an equilibrium state at a given temperature for addition of inert gases is $K_p=K_n\left(\frac{p}{\Sigma n}ight)^{\Delta n_g} $where, volume is constant, $\left(\frac{p}{\Sigma n}ight)$ remains constant for any value of $\Delta n_g$.
So, the given equilibrium reaction remains unaffected, if addition of inert Ar gas at constant volume.
