Ethanol can undergoes decomposition to form two sets of products ?
\[
\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}(\mathrm{g}) \longrightarrow\left[\begin{array}{l}
1 \\
\mathrm{C}_{2} \mathrm{H}_{4}(\mathrm{~g})+\mathrm{H}_{2} \mathrm{O}(\mathrm{g}) \quad \Delta \mathrm{H}=45.54 \mathrm{~kJ} \\
2 \\
\mathrm{CH}_{3} \mathrm{OHO}(\mathrm{g})+\mathrm{H}_{2}(\mathrm{~g}) \\
\Delta \mathrm{H}=68.91 \mathrm{~kJ}
\end{array}\right.
\]
if the molar ratio of \( \mathrm{C}_{2} \mathrm{H}_{4} \) to \( \mathrm{CH}_{3} \mathrm{CHO} \) is \( 8: 1 \) in a set of product gases, then the energy involved in the decomposition of 1 mole of ethanol is ?
(A) \( 65.98 \mathrm{~kJ} \)
(B) \( 48.137 \mathrm{~kJ} \)
(C) \( 48.46 \mathrm{~kJ} \)
(D) \( 57.22 \mathrm{~kJ} \)
