9. The diagram below is an example of a reaction coordinate diagram for a single step reaction. I abel the following and identify whether the reaction is endothermic or exothermic. Dang1 - reactanc encrgy level - product energy level - activation encrgy (Fi) - transition state or activated complex energy level - Hen 10. The Arrhenius equation shows the dependence of the rate constant on temperature and activation energy. Write the Arrhenius equation and define its terms k= terms: A=T=R=E= 11. An alternative form of the Arrhenius equation is found by taking the natural log of the above equation. Write the ln k version of the Arrhenius equation bekw. Note that this cquation has the form of a straight line (y=mx+b) if y is taken as ln k and x is taken as 1/T. If the rate constant for a reaction is measured as a function of temperature, a plot of ln k ws. 1/T will give a straight line with slope = In some case, when cither data are limited or plotting capabilities are absent, we can culculate the activation energy of a reaction by measuring the rate constant at two temperatures
