The rate coefficient (K) for a particular reactions is \[1.3\times {{10}^{-4}}{{M}^{-1}}{{s}^{-1}}\] at\[100{}^\circ C\], and \[1.3\times {{10}^{-3}}{{M}^{-1}}{{s}^{-1}}\] at\[150{}^\circ C\]. What is the energy of activation \[\left( {{E}_{a}} \right)\] (in kJ) for this reaction? (R = molar gas constant\[=8.314\text{ }J{{K}^{-1}}mo{{l}^{-1}}\])
