A sample of milk splits after $60\mathrm{}\mathrm{m}\mathrm{i}\mathrm{n}$ at $300\mathrm{}\mathrm{K}$ and after $40\mathrm{}\mathrm{m}\mathrm{i}\mathrm{n}$ at $400\mathrm{}\mathrm{K}$ when the population of Iactobacillus acidophilus in it doubles. The activation energy (in $\mathrm{kJ}/\mathrm{mol}$) for this process is closest to ______________.
