Question

Calculate the keq for the reversible reactions in  Cr2O72- (aq) + OH- (aq) -->  CrO42- (aq) + H2O  and  CrO42- (aq) ---> Cr2O72 given the ff. data:

 

                                HCrO4- --> H+ + CrO42-               K = 3.2 x 10-7

                             2 HCrO4- ---> CrO42- + H2O           K = 34

                                      H2O  H+ ---> + OH-              K = 1.0 x 10-14
