Chemical equilibrium is dynamic in nature because

For a reversible reaction involving two reactants,if the concentration of the reactants is doubled,the equilibrium constant will:

Addition of a catalyst in a system at equilibrium:

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:

When the rate of the forward reaction is equal to the rate of the backward reaction,the state is known as.......

For a reversible chemical reaction at equilibrium involving two reactants,if the concentrations of the reactants are doubled,what happens to the equilibrium constant $(K_c)$?
