An amount of solid 
is placed in a flask already containing ammonia gas at a certain temperature and 0.50 atm . pressure. Ammonium hydrogen sulphide decomposes to yield 
and 
gases in the flask. When the decomposition reaction reaches equilibrium, the total pressure in the flask rises to 0.84 atm . The equilibrium constant for 
decomposition at this temperature is
