Graphically determine activation energy
WebGraphically. We can graphically determine the activation energy by manipulating the Arrhenius equation to put it into the form of a straight line. Taking the natural logarithm of both sides gives us: ln [latex] \textit {k} = -\frac {E_a} {RT} + ln \textit {A} \ [/latex] A slight rearrangement of this equation then gives us a straight line plot ...
