What will be the effect of temperature on rate constant?

The rate of the chemical reaction doubles for an increase of $10 \mathrm{K}$ in absolute temperature from $298 \mathrm{K}.$ Calculate ${\mathrm{E}}_{\mathrm{a}}.$

The activation energy for the reaction $2\mathrm{H}\mathrm{I}\left(\mathrm{g}\right)\to {\mathrm{H}}_2\left(\mathrm{g}\right)+{\mathrm{I}}_2\left(\mathrm{g}\right)$ is $209.6 \mathrm{k}\mathrm{J} \mathrm{m}\mathrm{o}{\mathrm{l}}^{-1}$ at $581 \mathrm{K}.$ Calculate the fraction of molecules of reactants having energy equal to or greater than activation energy?
