## Knowing rate law equations

$aR \to bP, Rate = -\frac{1}{a} \frac{d[R]}{dt} = \frac{1}{b}\frac{d[P]}{dt}$

### Knowing rate law equations

On the class website, it has a link to some of rate laws
https://lavelle.chem.ucla.edu/wp-conten ... amples.pdf
I was wondering if it would be recommended to know and have a basic understanding of the differential and integrated rate laws for 1st, 2nd, and Zero Ordered reactions(bolded in the pdf) but if the derivations and such wouldn't be necessary to know. I know we still need to know how to rearrange the equation to solve for k or t or whatnot.

Oh, same question applies to the bolded equations for half life which are farther down in the document

It's a good idea to know the derivations so you know where these equations come from which will give you a better understanding of the concepts.

We probably won't be asked to show the derivations but just knowing them helps give a better understanding of the relationships which we will be asked about in the concept portion of the exam

I don't think he plans on making us derive any equations on his tests.

My TA said that it is a good idea to know, or at least understand the derivations.
