Equilibrium Constant Calculation for Decomposition of NH4HS:

Given Data:
- Initial pressure of ammonia gas (NH3): 0.50 atm
- Total pressure at equilibrium: 0.84 atm

Equilibrium Constant (Kp):
- The equilibrium constant (Kp) for the decomposition of NH4HS can be calculated using the expression:
Kp = (P(NH3) * P(H2S)) / P(NH4HS)

Pressure Calculation:
- At equilibrium, the total pressure is the sum of the partial pressures of NH3 and H2S:
P(total) = P(NH3) + P(H2S)

Partial Pressure Calculation:
- Since NH4HS decomposes into NH3 and H2S, the initial pressure of NH4HS will decrease by 'x', and the partial pressures of NH3 and H2S will increase by 'x'.
- Therefore, at equilibrium:
P(NH4HS) = 0.50 - x
P(NH3) = x
P(H2S) = x

Equilibrium Pressure Calculation:
- Given that the total pressure at equilibrium is 0.84 atm, we can substitute the partial pressures into the total pressure equation:
0.84 = 0.50 + 2x
2x = 0.34
x = 0.17 atm

Equilibrium Constant Calculation:
- Now, substitute the values of x into the equilibrium constant expression:
Kp = (0.17 * 0.17) / (0.50 - 0.17) = 0.11
Therefore, the equilibrium constant for the decomposition of NH4HS at this temperature is 0.11 (option 'A').
