![### Nitrogen and Hydrogen Reaction to Form Ammonia
Nitrogen and hydrogen react to form ammonia through the following exothermic reaction:
\[ N_2(g) + 3H_2(g) \rightarrow 2NH_3(g) \]
Suppose a mixture of \( N_2 \), \( H_2 \), and \( NH_3 \) has come to equilibrium in a closed reaction vessel. Predict the changes in the composition of the mixture and the direction of the equilibrium shift in response to the perturbations listed below:
### Table of Perturbations and Effects
| Perturbation | Change in Composition | Shift in Equilibrium |
|-------------------------------------|----------------------------------------------|-----------------------------|
| The temperature is lowered. | The pressure of \( N_2 \) will: | |
| | ◀ go up | ○ to the right |
| | ○ go down | ○ to the left |
| | ○ not change | ○ (none) |
| The temperature is raised. | The pressure of \( NH_3 \) will: | |
| | ⮟ | ○ to the right |
| | ⮛ | ○ to the left |
| | ⮟ | ○ (none) |
### Explanation
1. **When the temperature is lowered:**
- The equilibrium of the exothermic reaction will shift to the right (towards the formation of \( NH_3 \)) to produce more heat as a counteracting measure.
2. **When the temperature is raised:**
- The equilibrium of the exothermic reaction will shift to the left (towards the reactants \( N_2 \) and \( H_2 \)) to absorb the added heat.
Make sure to use this information to predict changes in the composition and direction of equilibrium during your experiments related to the formation of ammonia.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F1c542873-90da-4d8f-af03-4e4a6198699f%2F399c6201-aa95-4cf8-970b-247943485d62%2F7yplu1m_processed.jpeg&w=3840&q=75)
