Textbook Problem 5I.15
I am trying to do question 15 from section 5I in the textbook, which asks for the equilibrium concentrations of NH4HS(s) producing NH3 and H2S, both in gas form. The initial amount of NH3 and K are given. I was just wondering if the calculations would change at all other than the omission of the solid from the K setup (i.e. would the concentration of NH3 decrease?)

Re: Textbook Problem 5I.15
In this problem, since only NH4HS and NH3 were placed in the vessel without any H2S, we know the reaction must shift towards the right and thus the concentration of products must increase (otherwise the concentration of H2S would be negative). From here we know the concentrations of each product must increase by the same so we can set the change as '+x'. Thus, the equation for the equilibrium constant would be Kc = (0.2 M + x)(x) = 1.6 x 10^-4

Ok thanks so much. I did it this way and still have not been able to get the right answer, but maybe it is just a mistake with the actual calculations.
