## Rate Law

$\frac{d[R]}{dt}=-k[R]; \ln [R]=-kt + \ln [R]_{0}; t_{\frac{1}{2}}=\frac{0.693}{k}$

### Rate Law

For the final, do we need to know how to derive the first order reaction rate law or just how to identify and use it?

### Re: Rate Law

My TA said deriving the rate law was on one of the previous finals so you should know how to do it to be safe

### Re: Rate Law

On the outline it says know how to derive the rate law so a question involving/requiring derivation can potentially appear on the final.
