Topical Questions

These questions are keyed to the major topics in the chapter. Usually a question that is answered at the back of this book is paired with a similar one that is not.

The decomposition of NH₄HS is endothermic.

(a) Using Le Chatelier’s principle, explain how increasing the temperature would affect the equilibrium.

(b) If more NH₄HS is added to a sealed flask in which this equilibrium exists, how is the equilibrium affected?

(c) What if some additional NH₃ is placed in a sealed flask containing an equilibrium mixture?

(d) What will happen to the partial pressure of NH₃ if some H₂S is removed from the flask?
