An amount of solid $N{H_4}HS$ is placed in a flask already containing ammonia gas at a certain temperature and $0.50$ $atm.$ pressure. Ammonium hydrogen sulphide decomposes to yield $N{H_3}$ and ${H_2}S$ 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 $N{H_4}HS$ decomposition at this temperature is
