Activation Energies

Postby NatBrown1I » Wed Mar 13, 2019 1:44 pm

What is the difference between using (T'-T/T'T) and (1/T1-1/T2) for the activation energies? The textbook talks about one, but the solutions use both in different problems.

These are both the same expression, with T' = T2. If you simplify the expression by combining the fractions, you will get the same expression. I would suggest using the 1/T1-1/T2 because it's easier to keep track of everything.

they are both the same and will give the same value. it is up to you which is easier to visualize and use in the equation

They are both the same, choose which ever feels more natural to you and the one that makes more sense.
