Hello!
I'm really confused as to how to use the different forms of the Arrhenius equation when it comes to a problem (i.e. the exponential form vs. the logarithmic version). Does anyone have any tips/problem types that could demonstrate this? The equations get jumbled up in my head when I'm working w/this equation.

Re: Problem Types
From my understanding the exponential form is just a simplified version of the natural log form. You could derive one from the other and use either in order to find the same variable and get the same answer. I think Lavelle included both just to make that clear. Just use whatever is comfortable :)

Re: Problem Types
I find the exponential form the most useful because we often have to use this equation to solve for k or compare k values and it already has k isolated. However, as Blake said they are equivalent so it doesn't really matter you can just use whichever you are more comfortable with.

The Arrhenius equation is best used when looking for Ea or T. With the other form, they are in the exponent, and so eventually you have to reduce that other form to the Arrhenius equation anyways to get them out of the exponent.
