### Writing Equilibrium Equations for Reactions

This section guides you through writing the equilibrium constant expression (\( K \)) for several chemical reactions.

#### Part A

**Reaction:**
\[ \text{S}_2(g) + 2\text{H}_2(g) \rightleftharpoons 2\text{H}_2\text{S}(g) \]

**Options for Equilibrium Constant (\( K \)):**
1. \( K = \frac{[\text{H}_2\text{S}]^2}{[\text{S}_2][\text{H}_2]^2} \)
2. \( K = \frac{[\text{H}_2\text{S}]}{[\text{S}_2][\text{H}_2]} \)
3. \( K = \frac{[\text{H}_2\text{S}]^2}{[\text{S}_2]^2} \)
4. \( K = \frac{[\text{H}_2\text{S}]}{[\text{S}_2][\text{H}_2]^2} \)

#### Part B

**Reaction:**
\[ \text{H}_2\text{S}(aq) + \text{Cl}_2(aq) \rightleftharpoons \text{S}(s) + 2\text{HCl}(aq) \]

**Options for Equilibrium Constant (\( K \)):**
1. \( K = \frac{[\text{HCl}]^2}{[\text{Cl}_2][\text{H}_2\text{S}]} \)
2. \( K = \frac{[\text{Cl}_2][\text{H}_2\text{S}]}{[\text{HCl}]} \)
3. \( K = \frac{[\text{HCl}]}{[\text{Cl}_2]^2[\text{H}_2\text{S}]} \)

#### Part C

**Reaction:**
\[ \text{Br}_2(g) + \text{Cl}_2(g) \rightleftharpoons 2\text{BrCl}(g) \]

**Options for Equilibrium Constant (\( K \)):**
1. \( K = \frac{[\text{BrCl}]^2}{[\text

**Write the equilibrium equations for the following reactions:**

### Part B

**Reaction:**
\[ \text{H}_2\text{S(aq)} + \text{Cl}_2\text{(aq)} \rightleftharpoons \text{S(s)} + 2\text{HCl(aq)} \]

**Equilibrium Expressions:**

- \( K = \frac{[\text{HCl}]^2}{[\text{Cl}_2][\text{H}_2\text{S}]} \)
- \( K = \frac{[\text{S}][\text{H}_2\text{S}]^2}{[\text{HCl}]^2} \)
- \( K = \frac{[\text{Cl}_2][\text{H}_2\text{S}]}{[\text{HCl}]} \)
- \( K = \frac{[\text{HCl}]}{[\text{Cl}_2][\text{H}_2\text{S}]} \)

**Options to select from are formatted as bulleted lists with different equilibrium constant (K) expressions.**

### Part C

**Reaction:**
\[ \text{Br}_2\text{(g)} + \text{Cl}_2\text{(g)} \rightleftharpoons 2\text{BrCl(g)} \]

**Equilibrium Expressions:**

- \( K = \frac{[\text{BrCl}]^2}{[\text{Br}_2][\text{Cl}_2]} \)
- \( K = \frac{[\text{BrCl}]}{[\text{Br}_2][\text{Cl}_2]^2} \)
