### Born-Haber Cycle Calculation for Lattice Energy of ZnCl₂(s)

In addition to filling in the blanks below, show all of your work for this problem on paper for later upload.

Use the data provided to sketch the Born-Haber cycle for the formation of ZnCl₂(s) from Zn(s) and Cl₂(g), and then calculate the lattice energy for ZnCl₂(s). Carefully label each step of the cycle in your sketch.

#### Data Table:

| Process                          | Energy (kJ mol⁻¹) |
|----------------------------------|------------------|
| Bond dissociation (Cl₂(g))       | 242              |
| Heat of formation (ZnCl₂(s))     | -451             |
| Heat of sublimation (Zn(s))      | 131              |
| Electron Affinity (Cl(g))        | -349             |
| First Ionization Energy (IE₁) of Zn(g) | 906.4      |
| Second Ionization Energy (IE₂) of Zn(g) | 1733.3    |

### Instructions for Calculations:

1. **Bond Dissociation of Cl₂(g) to 2Cl(g):**
   \[ \text{Energy} = 242 \, \text{kJ mol}⁻¹ \]

2. **Sublimation of Zn(s) to Zn(g):**
   \[ \text{Energy} = 131 \, \text{kJ mol}⁻¹ \]

3. **Ionization of Zn(g) to Zn²⁺(g):**
   \[ \text{First Ionization Energy} = 906.4 \, \text{kJ mol}⁻¹ \]
   \[ \text{Second Ionization Energy} = 1733.3 \, \text{kJ mol}⁻¹ \]

4. **Electron Affinity of Cl(g) to Cl⁻(g):**
   \[ \text{Energy} = -349 \, \text{kJ mol}⁻¹ \]

**Total Electron Affinity for 2 moles of Cl:**
\[ 2 \times (-349) = -698 \, \text{kJ mol}⁻¹ \]

5. **Heat of Formation of ZnCl₂(s):**
   \[ \text{Energy} = -451 \, \text{kJ mol}⁻¹ \]
