Question: A.) Given the two reactions H 2 S(aq) HS (aq) + H + (aq), K 1 = 9.4610 8 , and HS (aq) S 2

A.) Given the two reactions

  1. H2S(aq) HS(aq) + H+(aq), K1 = 9.46108, and
  2. HS(aq) S2(aq)+H+(aq), K2 = 1.311019,

what is the equilibrium constant Kfinal for the following reaction?

S2(aq)+2H+(aq)H2S(aq) Kfinal =

B.) Given the two reactions

  1. PbCl2(aq) Pb2+(aq)+2Cl(aq), K3 = 1.811010, and
  2. AgCl(aq) Ag+(aq)+Cl(aq), K4 = 1.21104,

what is the equilibrium constant Kfinal for the following reaction?

PbCl2(aq) + 2Ag+(aq) 2AgCl(aq) + Pb2+(aq) Kfinal =
