## integrating equations

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

### integrating equations

Do we have to know the steps for integrating a 1st/2nd/0 order rate law or should we just focus on the equations that are derived from this? A problem showed up on Karen's worksheet, which I'm assuming is from a previous exam.

### Re: integrating equations

on the unit outlines, some bullet points do state that we should know how to derive certain equations (like integrated rate laws). I would know it just in case; Dr. Lavelle went over the process several times in lecture so it could definitely be something we're tested on.

### Re: integrating equations

My TA specified we should know how to integrate at least the first order equation.
