Select all of the correct statements about reaction quotients and equilibrium constants from the choices below.

A reaction quotient equals the equilibrium constant at equilibrium.



K changes as temperature changes, but is independent of concentrations.



If Q = K the reaction is already at equilibrium.



A reaction quotient is the same as an equilibrium constant.



The richer a reaction mixture is in product the higher its Q value is.


As a reaction approaches equilibrium its Q value rises and its K value falls until they are equal.
