The equilibrium constant, K, for the following reaction is 0.0833 at 324 K. NH4HS (s) <=> NH3(g) + H2S (g) An equilibrium mixture in a 10.7 L container at 324 K contains 0.257 mol NH4HS(s), 0.398 M NH3 and 0.209 M H2S. What will be the concentrations of the two gases once equilibrium has been reestablished, if the equilibrium mixture is compressed at constant temperature to a volume of 6.21 L? [NH3] = [H2S]=
