Using the bond enthalpy data given below, calculate the enthalpy change for the reaction
`C_(2)H_(4)(g)+H_(2)(g)rarrC_(2)H_(6)(g)`
`{:("Data":,"Bond",,"Bond enthalpy",),(,C-C,,336KJmol^(-1),),(,C=C,,606KJmol^(-1),),(,C-H,,410KJ mol^(-1),),(,H-H,,431KJ mol^(-1),):}`

Explanation

To calculate the enthalpy change for the reaction \( C_2H_4(g) + H_2(g) \rightarrow C_2H_6(g) \) using bond enthalpy data, we will follow these steps:

### Step 1: Identify the bonds in the reactants and products
- **Reactants**:
- \( C_2H_4 \) (Ethylene) has:
- 4 C-H bonds
- 1 C=C bond (double bond)
- \( H_2 \) (Hydrogen gas) has:
