The standard entropy change for the reaction
\( 4 \mathrm{Fe}(\mathrm{s})+3 \mathrm{O}_{2}(\mathrm{~g}) \rightarrow 2 \mathrm{Fe}_{2} \mathrm{O}_{3}(\mathrm{~s}) \) is \( -550 \mathrm{~J} \mathrm{~K}^{-1} \) at \( 298 \mathrm{~K} \).
[Given: The standard enthalpy change for the reaction is \( \left.-165 \mathrm{~kJ} \mathrm{~mol}^{-1}\right] \). The temperature in \( \mathrm{K} \) at which the reaction attains equilibrium is
