The rate coefficient ($k$) for a particular reaction is $1.3\times10^{-4}\,\mathrm{M}^{-1}\mathrm{s}^{-1}$ at $100^{\circ}\mathrm{C}$, and $1.3\times10^{-3}\,\mathrm{M}^{-1}\mathrm{s}^{-1}$ at $150^{\circ}\mathrm{C}$. What is the energy of activation ($\mathrm{E}_{\mathrm{A}}$) (in kJ) for this reaction? ($\mathrm{R}=$ molar gas constant $=8.314\,\mathrm{JK}^{-1}\mathrm{mol}^{-1}$)
