lnA

Why do you add lnA at the end of the Arrhenius equation? other than to make a linear plot, like other than for graphing purposes?

I’m pretty sure that’s the only real purpose of it because the equation is meant to be visualized on a graph.

The Arrhenius equation is usually k=Ae^(-Ea/RT). If you ln both sides you would get lnk=lnA- Ea/RT. This allows you to get a better view of the graph since it is in y=mx+b form. 1/T would be the x axis, lnk would be the y axis, and m would be -Ea/R.
