The enthalpy change $(\Delta \mathrm{H})$ for the reaction, $\mathrm{N}_{2}(\mathrm{~g})+3 \mathrm{H}_{2}(\mathrm{~g}) \longrightarrow 2 \mathrm{NH}_{3}(\mathrm{~g})$ is $-92.38 \mathrm{~kJ}$ at 298 $\mathrm{K}$. The internal energy change $\Delta \mathrm{U}$ at $298 \mathrm{~K}$ is (a) $-92.38 \mathrm{~kJ}$ (b) $-87.42 \mathrm{~kJ}$ (c) $-97.34 \mathrm{~kJ}$ (d) $-89.9 \mathrm{~kJ}$
