Conversion of Lime into Benzene

Explanation

To convert lime (CaO) into benzene (C6H6), we can follow these steps:

### Step 1: Formation of Calcium Carbide
1. **Starting Material**: We begin with lime, which is calcium oxide (CaO).
2. **Reaction with Carbon**: We react CaO with carbon (C) in the form of coke at a high temperature (2000 °C).
\[ \text{CaO} + 3\text{C} \rightarrow \text{CaC}_2 + \text{CO} \]
