Equilibrium constant is dependent only on temperature according to arrhenius theory and does not depend on the reaction extent, conversion or equilibrium position of a reversible chemical reaction because according to Le Chatelier's principle, doubling the reactants concentration will cause the equilibrium position to shift or adjust in a way as to annul or neutralize the effect of the external constraint (increasing or doubling the reactant's concentration).

K = Ae^-E/RT (Arrhenius equation).

Here, K is dependent on temperature and not on concentration.

If concentration of the reactants are doubled, then accordingly product will be formed without any change of equilibrium contant.
