<p>I am failing so hard.
. . .</p>
<p>Test #3:
- Why isn't the graph of pressure vs. volume a linear relationship? I thought it was a straight line rather than a curve.
- Kinetic energy vs. temperature is a bell curve?
- High boiling point = low vapor pressure?
- Arrhenius bases donate OH-? I thought they accepted H+.</p>
<p>pressure is inversely proportional to volume so it’s a curve, linear is when things are directly proportional. unless you put one of the variables over 1 (eg. 1/volume or 1/pressure) then the curve becomes a line.
The bell curve is the boltzmann’s distribution and shows how much energy particles possess at various temperatures.
The definition of arrhenius base is that they increase the concentration of OH in solutions.</p>
<p>High vapor pressure means that the substance is very volatile. The intermolecular forces are not strong enough to keep molecules from going from a liquid to a vapor state. Therefore, a very low boiling point. Conversely, a low vapor pressure indicates a high boiling point. </p>
<p>Sparknotes’ Tests are much harder than SAT II Chem Test in my opinion. Although I have not yet taken it, I know that Princeton Review’s are closest to the actual test. Missing 8-10 on Sparknotes but only 3-4 in PR. So do not worry about missing too many on the Sparknotes Practice Tests. Good luck!</p>
<p>Thank you both, I get it now!</p>
<p>@bio1995:
That makes me feel a lot better, woohoo!</p>
<p>There’s LOTS of stoich on that test. I took it last year.</p>
<p>hopefully this year also kamen. i could use the stoich for free points.</p>
<p>is sig figs on this test btw?</p>
<p>Yea there was one question when I took it last year. It was easy though don’t worry.</p>
