Chapter 12, Problem 25QAP
Consider the decomposition of ammonium hydrogen sulfide:
In a sealed flask at 25°C are 10.0 g of 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 for the decomposition of NH4HS at 25°C.
