Determination of Kc I - Video Solution

Given the reaction:  Ag+(aq)  +  2 NH3(aq) ≡  Ag(NH3)2+(aq)   Kc = 1.5×107, what are the numerical values of Kc for the reactions below?

A.  ½ Ag(NH3)2+(aq)  ≡  ½ Ag+(aq)  +  NH3(aq)                 Kc’ = 0.00026

B.   3 Ag+(aq)  +  6 NH3(aq) ≡  3 Ag(NH3)2+(aq)                Kc’’ = 3.4 x 1021
