Consider the reaction $\mathrm{CO}(\mathrm{g})+\frac{1}{2} \mathrm{O}_{2}(\mathrm{g}) \rightarrow \mathrm{CO}_{2}(\mathrm{g})$. The value of $\Delta \mathrm{U}$ for the reaction at 300 K is $-281.8 \mathrm{kJ} \mathrm{mol}^{-1}$. The value of $\Delta \mathrm{H}$ at same temperature is ____ $\mathrm{kJ} \mathrm{mol}^{-1}$ (rounded up to the first decimal place).

\[ \left[\mathrm{R}=8.3 \mathrm{J} \mathrm{K}^{-1} \mathrm{mol}^{-1}\right] \]
