Consider the decomposition of ammonium hydrogen sulfide:

In a sealed flask at 25 °C are 10.0 g NH₄HS, ammonia with a partial pressure of 0.692 atm, and H₂S with a partial pressure of 0.0532 atm. When equilibrium is established, it is found that the partial pressure of ammonia has increased by 12.4%. Calculate K_P for the decomposition of NH₄HS at 25 °C.
