The solid NH4HS is in equilibrium with the gases NH3 and H2S. An equilibrium mixture contains solid NH4HS, 0.12 M NH3 and 0.021 M H2S.
NH4HS(s)<>NH3(g)+H2S(g).
a) What is the value of the equilibrium constant Kc for the reaction?
b) What is the effect of adding more solid NH4HS to the equilibrium mixture?
c) What is the effect of increasing the volume of the container?
