Question

**Educational Content: Understanding Chemical Equilibrium Changes**

In this exercise, we explore how the concentration of each species in a chemical reaction changes to reestablish equilibrium after alterations in the system. The reaction under consideration is:

\[ \text{H}_2(g) + \text{Br}_2(g) \rightleftharpoons 2\text{HBr}(g) \]

**Instructions**:
- Use the arrows to determine the change in concentration for each species:
- An **up arrow** (↑) signifies an increase in concentration.
- A **down arrow** (↓) indicates a decrease in concentration.
- Leaving it blank means no change in concentration.

**Scenario Analysis**:
1. If the concentration of H₂ is decreased:
- \[ \text{H}_2: \quad \downarrow \]
- \[ \text{Br}_2: \quad \uparrow \]
- \[ \text{HBr}: \quad \downarrow \]

2. If the concentration of HBr is increased:
- \[ \text{H}_2: \quad \uparrow \]
- \[ \text{Br}_2: \quad \uparrow \]
- \[ \text{HBr}: \quad \downarrow \]

**Answer Bank**:
The representation uses boxes below the molecular formulas and allows for the selection of the appropriate arrows based on reaction changes, guiding students through the process of visualizing equilibrium shifts in concentrations.
