Can the Arrhenius equation be written as LNK?
Often the equation is written in logarithmic form lnk=lnA – E a/RT A graph of lnk against 1/T is a straight line with a gradient –E a/R and an intercept on the lnk axis of lnA.
It is named after Svante Arrhenius.What is ln in Arrhenius equation?
Using this straight line, which is referred to as an Arrhenius plot, Arrhenius created the equation: ln(k) = (-Ea/R)(1/T)+ln(A), where ln(k) is the y variable, 1/T is the x variable, -Ea/R is the slope, and ln(A) is the y-intercept.
The Arrhenius law predicts that the motion of the structural units (atoms, molecules, ions, etc.) should slow down at a slower rate through the glass transition than is experimentally observed.
In other words, the structural units slow down at a faster rate than is predicted by the Arrhenius law.
