Problem Details

The equilibrium constant for the overall reaction:

Ag+(aq) + 2NH3(aq) ⇌ Ag(NH3)2+(aq)

is known to be Kc = 1.105x107. This reaction occurs in two steps corresponding to the addition of the first and then the second ammonia molecules. You have been able to measure the equilibrium constant for the first step:

Ag+(aq) + NH3(aq) ⇌ Ag(NH3)+(aq)     Kc = 1.7x103

What is the equilibrium constant for the second step?

a) 9.7x10−7

b) 2.3x105

c) 1.88x1010

d) 1.54x10−3

e) 6.5x103
