Conversion of Ethyne into ethane

Explanation

To convert ethyne (C2H2) into ethane (C2H6), we can follow these steps:

### Step 1: Hydrogenation of Ethyne to Ethene
1. **React Ethyne with Hydrogen**: Ethyne (C2H2) is treated with hydrogen gas (H2) in the presence of a nickel catalyst (Ni) at a temperature of 250 degrees Celsius.
2. **Chemical Reaction**: The reaction can be represented as:
\[ \text{C}_2\text{H}_2 + \text{H}_2 \xrightarrow{\text{Ni}, 250^\circ C} \text{C}_2\text{H}_4 \]
