Re: derivations
In lecture I think he derived the first, second, and zero rate laws. I think he said in lecture that he wasn't going to do it for the Arrhenius equation. I'm not entirely sure though.
Re: derivations
Confirmed, Professor Lavelle did not go over the derivations for Arrhenius, however, he did go over the derivations for 0,1,and 2nd order reactions and their half-life reactions. I don't think they'll be essential to know, but a good foundation to how things work if there is a concept heavy question on the final.

Re: derivations
I would focus on the derivations that were given in class, specifically those for 1, 2, and 0 order.

Re: derivations
Make sure to look at your notes for the first rate, second rate, and zero rate reactions. They're all pretty similar but it's important to know where they come from, especially when looking at the half life equations.
Re: derivations
Derivations can also be helpful to know if you need to manipulate formulas on a test only given certain information. I think knowing the relationship between [A], ln[A], and 1/[A] and time (t) is also useful (specifically the graphs and how they relate to slope)

Re: derivations
On the Kinetics outline Lavelle lists:
Know how to derive the differential and integrated rate laws for zero, 1st and 2nd order reactions
Use the Arrhenius equation and rate constants measured at different temperatures to determine activation energy.
Use the Arrhenius equation and the activation energy to find the rate constant at a given temperature
He explicitly lists to know the derivation of the rate laws, but only says to know how to use the Arrhenius equation.

Re: derivations
I believe that knowing the derivation of the rate laws and even the half lives is important to develop a proper understanding, however, Dr. Lavelle did not go over the derivation of the Arrhenius equation in class.

Re: derivations
I don't think you need to know how to derive any. He has said "know how to derive" on every outline but has never asked for just a derivation on a test.
