The number of molecules with energy greater than the threshold energy for a reaction increases five fold by a
\( \mathrm{P} \) rise of temperature from \( 27^{\circ} \mathrm{C} \) to \( 42^{\circ} \mathrm{C} \). Its energy of

W activation in \( \mathrm{J} / \mathrm{mol} \) is
(Take In \( 5=1.6094 ; \mathrm{R}=8.314 \mathrm{~J} \mathrm{~mol}^{-1} \mathrm{~K}^{-1} \) )
