  1. VI. The Equilibrium Constant • p. 57 - 60

  2. The Equilibrium Constant, Keq • A(g) + B (g) = C (g) + D (g) • Keq = [Products] = • [Reactants]

  3. 2A (g) + 3B (g) = 2C(g) + D (g) • Keq =

  4. Not Included in Keq: • solids • pure liquids • when only 1 liquid exists on both sides of the equilibrium expression (if >1 they mix)

  5. 3A(s) + B(g) = 2C(g) + D(l) • Keq = • because solids and pure liquids have a constant [ ], adding them will have NO EFFECT on the equilibrium (NO SHIFT will occur)

  6. VII. Le Chatelier’s Principle & Keq • p. 61 - 63

  7. Only Temperature Change can affect Keq: • Temperature, concentration, pressure, surface area can cause rx rate to change • Temperature, concentration, pressure can cause shifts in equilibrium • BUT, the value of Keq remains constant once equilibrium is re-established

  8. What do Keq values mean? • a large Keq = a large amount of product is present at equilibrium • a small Keq = a small amount of product is present at equilibrium

  9. If a temperature change causes a: • shift towards products, the Keq will... • shift towards reactants, the Keq will ...
