### Chemical Equilibrium: The Haber Process

#### Reaction Overview
The Haber process is an industrial method for synthesizing ammonia (NH₃) from nitrogen gas (N₂) and hydrogen gas (H₂). The chemical equilibrium involved in this process can be represented by the following equation:

\[ \text{N}_2(\text{g}) + 3\text{H}_2(\text{g}) \rightleftharpoons 2\text{NH}_3(\text{g}) + \text{heat} \]

This indicates that the formation of ammonia is exothermic, releasing heat.

#### Example Problem: Impact of Adding Ammonia

**Scenario:**
1. **Ammonia (NH₃) is added.**

When ammonia is added to the system, according to Le Chatelier’s Principle, the equilibrium will shift in the direction that opposes the change. In this case:

**Dropdown Choice Explanation:**
- The possible options could include shifting towards reactants, shifting towards products, or no change.
- Select the correct option based on the following principles.

By adding ammonia, the system will seek to reduce the concentration of NH₃ by shifting the equilibrium to the left, favoring the production of nitrogen (N₂) and hydrogen (H₂) and hence absorbing some of the added ammonia.

\[ \text{N}_2(\text{g}) + 3\text{H}_2(\text{g}) \leftarrow 2\text{NH}_3(\text{g}) + \text{heat} \]

This adjustment helps the system counteract the disturbance and restore a new equilibrium state.
