(21) Consider the equilibria below and choose the statement that is NOT true. C₂04² (aq) + H3O+ H₂O(1) + HC₂O4 (aq) Fe³(aq) + C₂04² (aq) [Fe(C₂O4)3] (aq) (A)) Kb = 6.7 x 10-11 K = 2 x 10²0 The second equilibrium will be shifted left by the addition of acid The first equilibrium will be shifted left by the addition of (B) Fe³(aq) (0) Neither equilibrium will be affected if the solutions are buffered to a pH = 7.00 (D) The second equilibrium heavily favors the products (E) The first equilibrium heavily favors the reactants
