When we plot the points of amount of product produced vs time, for the same reaction at two different temperatures, we get a graph like the one shown below:

where * α* SD

RS is the conversion factor between the reactant state and saddle domain, while * k* SD is the rate constant from the saddle domain. The first can be simply calculated from the free energy surface, the latter is easily accessible from short molecular dynamics simulations [3]
