When solid NH4HS is vaporized and maintained at 20 C the following equilibrium established NH4HS s NH3 g H S g and the total pressure is 0 4 atm When vaporiz in the presence of NH3 in a closed vessel at 20 C the partial pressure of NH3 was 0 5 atm Calculate under equilibrium the mole fractions of NH3 g and H S g A 0 93 0 07 B 0 6 0 4 C 0 75 0 247 D 0 66 0 34
