use the chemists' definition of a critical point.
Hi guys, I've been working on this problem for so long but I cannot figure out how to approach it...what am I supposed to do? Here is the question, and what I have tried...
(Background info is included so you know what's going on...)
What I've done: b) I've taken the derivative of the van der Waals gas equation to get 2a/v^3 - RT/(v-b)^2
Thanks so much to anyone that can help!
Wait a minute, wouldn't 2RT/(v-b)^3 - 6a/v^4 would be the inflection point for the van der Waals gas? That's actually the next question and what I had done. However, when I get to the last question in that series I have no idea what to do, which is why I was questioning my first two results.
