### Hydrogenation Reaction and Enthalpy Calculation**Hydrogenation of Ethylene:**Compounds with carbon–carbon double bonds, such as ethylene (C₂H₄), undergo a reaction called hydrogenation where they add hydrogen (H₂) to form ethane (C₂H₆):\[ \text{C}_2\text{H}_4(g) + \text{H}_2(g) \rightarrow \text{C}_2\text{H}_6(g) \]**Objective:**Calculate the enthalpy change (ΔH) for the hydrogenation reaction using the provided combustion data.**Combustion Data:**1. **Combustion of Ethylene:** \[ \text{C}_2\text{H}_4(g) + 3\text{O}_2(g) \rightarrow 2\text{CO}_2(g) + 2\text{H}_2\text{O}(l) \] \[ \Delta H = -1411 \, \text{kJ} \]2. **Combustion of Ethane:** \[ \text{C}_2\text{H}_6(g) + \frac{7}{2}\text{O}_2(g) \rightarrow 2\text{CO}_2(g) + 3\text{H}_2\text{O}(l) \] \[ \Delta H = -1560 \, \text{kJ} \]3. **Combustion of Hydrogen:** \[ \text{H}_2(g) + \frac{1}{2}\text{O}_2(g) \rightarrow \text{H}_2\text{O}(l) \] \[ \Delta H = -286 \, \text{kJ} \]**Explanation:**This section provides the chemical equations and associated enthalpy changes for the combustion reactions of ethylene, ethane, and hydrogen. To find the enthalpy change of the hydrogenation reaction, apply Hess's Law using the given values.
