The rate of a reaction quadruples when the temperature changes from $\displaystyle 300$ to $\displaystyle 310$ K. The activation energy of this reaction is :
(Assume activation energy and pre-exponential factor are independent of temperature; $\displaystyle \ln 2=0.693 ; \mathrm{R}=8.314 \mathrm{~J}$ $\displaystyle \mathrm{mol}^{-1} \mathrm{~K}^{-1}$ )
Official answer
(1)
$\displaystyle 107.2 \mathrm{~kJ} \mathrm{~mol}^{-1}$
