![**Chemical Equilibrium and Le Chatelier's Principle**
The following system establishes an equilibrium at 545 K:
\[ \text{NH}_4\text{HS (s)} \rightleftharpoons \text{NH}_3 (g) + \text{H}_2\text{S (g)} \]
\[ \Delta H^\circ > 0 \]
Briefly explain the effect in terms of the expected shift (toward reactant, toward product, or no change) of each of the following:
a. **The volume of the container is doubled.**
b. **The temperature of the system is raised to 825 K.**
c. **Some additional solid \(\text{NH}_4\text{HS}\) is added.**
d. **The reaction flask has 1.25 atm of the inert gas argon added to it.**
Explanation of Graphs and Diagrams:
In this specific text, there are no graphs or diagrams present. If there were, a detailed description would be provided to enhance understanding. Visual aids often include plots of concentration vs. time or pressure vs. volume, which can help illustrate the dynamic nature of equilibrium and responses to changes in conditions based on Le Chatelier's Principle.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fbca33481-84f0-4d0e-9458-2fdcb949c0ec%2Ff686deb2-3e68-4b9a-af6b-044106e1f71b%2F29t7v0e_processed.jpeg&w=3840&q=75)
