The rate coefficient (k) for a particular reactions is $\;1.3 \times 10^{-4}\;M_{-1}s^{-1} \;$ at $\;100^{0}C\;$ , and $\;1.3 \times 10^{-4}\;M_{-1}s^{-3} \;$ at $\;150^{0}C\;$ . What is the energy of the activation $\;(E_{A})\;$ (in kJ) for this reaction ? (R = molar gas constant=8.314$\;JK^{-1} mol^{-1}\;$)
