<p>Hi, I was wondering how necessary it is to memorize equations for AP Chemistry exam? I know that we get a list of them for the free response, but do we need to memorize them for the multiple choice? (That would seem silly to me since we do not have the calculator on the multiple choice)</p>

<p>Thanks!</p>

<p>There are a couple like PV=nRT and effusion through a pinhole that work in a sense of which choice has the biggest or smallest value for a variable.</p>
