Step-by-step solution

2 steps

Identify the reactants and products for Step 2.
Step 2 shows the conversion of Ethene to Ethane. Ethene ( $\text{C}_2\text{H}_4$ ) is an alkene, and Ethane ( $\text{C}_2\text{H}_6$ ) is an alkane. This is a hydrogenation reaction.
Determine the reagents and conditions for hydrogenation.
Hydrogenation involves adding hydrogen across a double bond.
- Reagent: Hydrogen gas ( $\text{H}_2$ )
- Conditions: A catalyst (such as Nickel, Platinum, or Palladium) and heat (typically around $150^\circ\text{C}$ to $200^\circ\text{C}$ for Nickel).
The reagents and conditions used in Step 2 are:
$\boxed{\text{Hydrogen gas (H}_2\text{) and Nickel catalyst at } 150^\circ\text{C} - 200^\circ\text{C}}$
