I know at stp the most ideal would be O2 and the C2H4 but I'm not for sure when pressure is high
Would the answer be D. C?
Have you studies van der waals equation and constants?
Yeah a little bit.
Do you see a trend in the constants of these substances?
What trend do you see and what do you think it means?
The bonds are decreasing from A to B? So I think that D. C would have ideal behavior at high pressures.
What do you mean that the bonds are decreasing?
A has more bonds than B, C, and D.
That is true. Are you saying that oxygen gas will be most ideal at high pressures?
Well I think Ne would have ideal behavior at high pressures. Or O-O. Am I correct?
Yes, I get one of those. Do you have the van der waals constants for each?
No. But I think it's O-O, not Ne.
http://chemed.chem.purdue.edu/genchem/topicreview/bp/ch4/deviation5.html Why do you think it is O-O?
I think because it has one bond...
Why does that make it more ideal at high pressures do you think?
Maybe because the one bond makes it more stable and it's between O and O?
Hm, let's look at the constants for O2 and Ne and see if we can draw any conclusions.
What values of constants do you think would make the van der waals equation simplify down to the ideal gas law?
I'm not really sure...
If the an^2/V^2 term went to 0, what do you think would happen to van der waals?
I'm not sure. Can you please explain?
If that term went to zero, then van der waals would simplify to|dw:1438902988176:dw|
And what if the nb term went to 0?
Um idk... /:
Take a guess.|dw:1438903094158:dw|
No, only the nb term would go to zero.|dw:1438903183657:dw|
Ohh okay! So it's Ne?
Right, because the van der waals constants are closer to 0.
Ah, okay! Thank you so much for explaining it!
You're welcome :-)
