<p>Any predictions on the equilibrium free response?</p>
<p>I bet it's an equilibrium hehe.</p>
<p>Guessing it's on gases or ksp...maybe buffers...please no buffers.</p>
<p>Ksp was last year.</p>
<p>Was it? Well it's probably gases...(easy stuff)...they haven't done that for like four years.</p>
<p>yeah probably gases...you don't think they'll bust out another acid/base?</p>
<p>I hope it's acid/base... I like those more than gas. Although gases aren't bad either.</p>
<p>yeah acid/base are def the best, although ksp's are cake, too.</p>
<p>No, but I know what 1a will be! It'll be: "write the Equilibrium expression for the above reaction." Or something along those lines...</p>
<p>And does anyone want to explain what they mean by "it'll be about gases"? How do you do equilibrium for gases...what am I missing?</p>
<p>It's the same as any other equilibrium but you use the partial pressure of each gas instead of concentration.</p>
<p>And also, Kp=Kc(RT)^(change in moles of gas)</p>
