The value of enthalpy change \((\Delta H)\) for the reaction \(\mathrm{C}_2 \mathrm{H}_5 \mathrm{OH}(l)+3 \mathrm{O}_2(\mathrm{~g}) \longrightarrow 2 \mathrm{CO}_2(\mathrm{~g})+ 3 \mathrm{H}_2 \mathrm{O}(l)\), at \(27^{\circ} \mathrm{C}\) is \(-1366 \cdot 5 \mathrm{~kJ} \mathrm{~mol}^{-1}\). The value of internal energy change for the above reaction at this temperature will be
