7/03/2009 · How to plot with Arrhenius equation.? okay I've finally struck an issue when im try to plot the graph of lnk against 1/T. Problem is i don't know how to find the values for lnk inorder to plot it. I've tried several times with my results by putting them into the rate equation but i keep geting very indecisive rate constants back. how to do order by in hive 26/07/2008 · Best Answer: You should be plotting ln(k) vs 1/T. Make sure T is in Kelvins. A downward sloping straight line should be obtained, with the intercept = ln(A), and the slope = -Ea/R. These plots are a little confusing, since 1/T's are very small numbers and the plot …

The activation energy may then be extracted from a plot of ln k vs. 1/T, which should be linear. This plot is called an "Arrhenius plot". This plot is called an "Arrhenius plot". Problem MK1.1. how to make an xy scatter plot with multiple legends do this, you will first need to recast the Arrhenius equation so that it is in a linear form: y =α+ β x (2) where y is a function only of k , and x is a function only of T (this is called linearizing the

## How To Make An Arrhenius Plot

The Arrhenius equation is a formula for the temperature dependence of reaction rates. The equation was proposed by Svante Arrhenius in 1889, based on the work of Dutch chemist Jacobus Henricus van 't Hoff who had noted in 1884 that van 't Hoff equation for the temperature dependence of equilibrium constants suggests such a formula for the rates of both forward and reverse reactions.
