Calculate the bond energy of `C - H` bond, given that the heat of formation of `CH_4`, heat of sublimation of carbon and heat of dissociation of `H_2` are `-74.8 + 719.6 and 435 kJ mol^(-1)` respectively.

Explanation

To calculate the bond energy of the C-H bond in methane (CH₄), we will use the provided thermodynamic data: the heat of formation of CH₄, the heat of sublimation of carbon, and the heat of dissociation of H₂.

### Step-by-Step Solution:

1. **Write the Reaction for the Formation of CH₄**:
The formation of methane can be represented as:
\[
C(s) + 2H_2(g) \rightarrow CH_4(g) \quad \Delta H = -74.8 \, \text{kJ/mol}
