Calculate the bond energy of H-Cl bond, given that the bond energies of H–H, CI—Cl bonds are `433 kJ mol^(-1) and 242 kJ mol^(-1)` respectivly. The `DeltaH_f` for HCl is -91 `kJ" " mol^(-1)`.

Explanation

To calculate the bond energy of the H-Cl bond, we will use the given bond energies of H-H and Cl-Cl, as well as the enthalpy of formation (ΔH_f) of HCl. The steps are as follows:

### Step 1: Write the bond dissociation equations
1. The bond dissociation of hydrogen gas (H2) into hydrogen atoms:
\[ \text{H}_2(g) \rightarrow 2 \text{H}(g) \quad \Delta H = +433 \text{ kJ/mol} \]
