Question

21. Ammonium hydrogen sulphide dissociate as follows NH4HS(s) <=>NH3(g)+H2S(g), if solid NH4HS is placed in an evacuated flask at certain temperature it will dissociate until the total pressure is 600 torr. (a) calculate the value of equilibrium constant for the dissociation reaction. (b) additional NH3 is introduced into the equilibrium mixture without changing the temperature until partial pressure of NH3 is 750 torr, what is the partial pressure of H2S under these conditions? What is the total pressure in the flask?
