The activation energy for the gas phase decomposition of dinitrogen pentoxide is \( 103 \mathrm{~kJ} \). \[ \mathrm{N}_{2} \mathrm{O}_{5} \rightarrow 2 \mathrm{NO}_{2}+1 / 2 \mathrm{O}_{2} \] The rate constant at \( 322 \mathrm{~K} \) is \( 8.12 \times 10^{-4} \mathrm{~s}^{-1} \). The rate constant will be \( 0.00918 \mathrm{~s}^{-1} \) at
