The rate constant of a first order reaction, $\mathrm{X} \rightarrow \mathrm{Y}$, is $1.6 \times 10^{-1} \mathrm{s}^{-1}$ at 300 K . Given that the activation energy of the reaction is $28 \mathrm{kJ} \mathrm{mol}^{-1}$ and assuming Arrhenium behaviur for the temperature dependence, the total time required to obtain $90 \%$ of Y at 350 K is ____ s(Upto to one decimal place, use $\mathrm{R}=8.31 \mathrm{JK}^{-1} \mathrm{mol}^{-1}$ ).
