CI.2 Flashcards
Equilibrium constants and the effect of changes in conditions
Is there a set unit for the equilibrium constant Kc?
No, it depends on the reaction and the equilibrium expression.
What is meant by dynamic equilibrium?
The rate of forward reaction is equal to the rate of backward reaction in a closed system.
Changes in the concentration or pressure will alter what aspect of the equilibrium?
The composition of the equilibrium mixture itself.
Will changes in the concentration and pressure of an equilibrium system alter the equilibrium constant Kc?
No, Kc will be constant regardless of pressure and concentration.
Will changes in temperature alter the equilibrium constant Kc?
Yes, temperature will affect Kc.
Will the presence of a catalyst affect the equilibrium in any way?
No, catalysts do not affect the position of equilibrium or the equilibrium constant, it also has no effect on the composition of the equilibrium mixture. It only speeds up the rate at which equilibrium is attained.
Does temperature have an effect on the composition of the equilibrium mixture?
Yes.
