Taking the logarithm of both sides allows it to be put in a linear form, which proves to clearly illustrate the dependence of the rate constant on temperature and, of course, on activation energy.  
Building on the kinetic theory of gases, it was originally formulated by J.J. Hood, although its namesake later provided a true theoretical basis for it.  The collision frequency Z is only weakly dependent on temperature, while the steric factor P is always less than one.  Taking the logarithm of both sides allows it to be put in a linear form, which proves to clearly illustrate the dependence of the rate constant on temperature and, of course, on activation energy.  FTP, name this equation of chemical kinetics, named for a Swedish scientist.
