Question

Write the equilibrium constant expression for the dissolution ofammonia in water NH3 (g) <-> NH3 (aq)

K=57.5

Use this equilibrium constant expression to estimate the partialpressure of NH3 (g) over a solution containing 5 X10^-9 M NH3 (aq).These are conditions similar to that found for acid rains with ahigh ammonium ion concentration.

I think the Kc for the reaction would be Kc= [NH3]/[NH3] whichwould equal 1. But how do you get the partial pressure from theinformation given?
