For the reaction:
`2H_(2)(g) +O_(2)(g) rarr 2H_(2)O(g), DeltaH =- 571 kJ`
bond enegry of `(H-H) = 435 kJ` and of `(O=O) = 498 kJ`. Then, calculate the average bond enegry of `(O-H)` bond using the above data.

Options

A. `484 kJ`
B. `-484 kJ`
C. `271 kJ`
D. `-371 kJ`

Explanation

To calculate the average bond energy of the O-H bond for the reaction:

\[ 2H_2(g) + O_2(g) \rightarrow 2H_2O(g) \]

with the given data:

- \(\Delta H = -571 \, \text{kJ}\)
- Bond energy of \(H-H = 435 \, \text{kJ}\)
