A second order reaction in ethanoic solution has a prefactor of 10^13 hz and an activation energy of 0.9 eV. Draw an Arrheniusplot over the range of possible reaction temperatures(between the freezing and boiling point of ehtanol). If you have an initialconcerntration of 0.01 mol/liter of its reactant, how long does thereaction need to proceed to 90% compleation. Make a plot for this duration over the same temperature range. Use logarithmic scale on the y axis. You van use xcel or similar software to solve this problem and genreate the plots.
