The rate of a reaction quadruples when the temperature changes from $293\text{ K}$ to $313\text{ K}$. Calculate the energy of activation of the reaction, assuming that it does not change with temperature. $(\log 2 = 0\cdot30, \log 4 = 0\cdot60) [\text{R} = 8\cdot314\text{ J K}^{-1}\text{ mol}^{-1}]$
