The value of enthalpy change \( (\Delta \mathrm{H}) \) for the reaction
\[
\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}_{(\ell)}+3 \mathrm{O}_{2(\mathrm{~g})} \rightarrow 2 \mathrm{CO}_{2(\mathrm{~g})}+3 \mathrm{H}_{2} \mathrm{O}_{(\ell)}
\]
at \( 27 \mathrm{C} \) is \( -1366.5 \mathrm{~kJ} \mathrm{~mol}^{-1} \). The value of internal energy change for the above reaction at this temperature will be :-
(1) \( -1371.5 \mathrm{~kJ} \)
(2) \( -1369.0 \mathrm{~kJ} \)
(3) \( -1364.0 \mathrm{~kJ} \)
(4) \( -1361.5 \mathrm{~kJ} \)
