Presence of catalysis does not change equilibrium constant. Why?

At a given temperature, for a reversible reaction, if the concentration of reactants is doubled then the equilibrium constant will

Chemical equilibrium is dynamic. Why?

Explain the relationship between Gibbs energy change and equilibrium constant.

What property of a reaction can be used to predict the effect of a change in temperature on the magnitude of an equilibrium constant?

Write the characteristics of equilibrium constant.

In a reversible reaction, if the concentration of reactants are double, the equilibrium constant K will be x times the initial equilibrium constant. x will be equal to

The equilibrium constant for the reaction N_(2(g)) +O_(2(g)) hArr 2NO_((g)) is 4 xx 10^(-4) at 200K. In presence of a catalyste, equilibrium is attaincd ten times faster. Therefore, the equilibrium constant in the presence of the catalyst at 200K is
