Select the incorrect statement $(s)$ regarding the state of equilibrium.

In a chemical reaction,equilibrium is established when:

The equilibrium constant for the reaction ${N_{2(g)}} + {O_{2(g)}} \rightleftharpoons 2NO_{(g)}$ at $2000 \, K$ is $4 \times 10^{-4}$. If the equilibrium is attained $10$ times faster in the presence of a catalyst,the equilibrium constant at $2000 \, K$ in the presence of the catalyst will be .................

In a reversible reaction at equilibrium between two reactants,if the concentration of the reactants is doubled,the equilibrium constant ..........

For the reaction $2 \ HI_{(g)} \rightleftharpoons H_{2(g)} + I_{2(g)} - Q \ kJ$,the equilibrium constant depends upon

The equilibrium constant for the reaction $N_{2(g)} + O_{2(g)} \rightleftharpoons 2NO_{(g)}$ is $4 \times 10^{-4}$ at $2000 \ K$. In the presence of a catalyst,the equilibrium is attained ten times faster. Therefore,the equilibrium constant in the presence of a catalyst at $2000 \ K$ is:
