The polymerisation of ethylene to linear polyethylene is represented by the reaction
`nCH_(2)=CH_(2)rarr(-CH_(2)-CH_(2)-)_(n)`
When `n` has a large integral value. Given theat the average enthalpies of bond dissociation for `C=C` and `C-C` at `298K`are `+590` and `+331kJ mol^(-1)` respectively, calculate the enthalpy of polymerisation per mole of ethylene at `298K`.

Explanation

To calculate the enthalpy of polymerization per mole of ethylene at 298 K, we will follow these steps:

### Step 1: Understand the Reaction
The polymerization of ethylene (C₂H₄) can be represented as:
\[ n \text{C}_2\text{H}_4 \rightarrow (-\text{CH}_2-\text{CH}_2-)_{n} \]
This means that `n` molecules of ethylene combine to form a polymer chain of polyethylene.

### Step 2: Identify Bond Dissociation Energies
