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.

K is the highest value that Q can have.

The value of K does not change as a reaction progresses toward equilibrium.

A reaction quotient is the same as an equilibrium constant.

As a reaction progresses backward toward equilibrium Q drops.
