Re: Midterm 2013 Q4A

Also, is it still possible to use the volume variation instead? I used it the first time around and came out with the same answer.

Midterm 2013 Q4A

To calculate the work from B to C, it appears a variation of the work equation was used. Instead of volume, pressure values were used instead. Why is pressure used instead of the volume? They both change, so how would I go about determining which variation of the work equation to use? Also, in the s...

staggered vs eclipsed stability

I think I just misheard Dr. Lavelle in lecture, but I kind of confused myself as to why a molecule favor an eclipsed position as opposed to a staggered position? In my head, I guess I rationalized that the electron densities would favor a staggered state because of election - electron repulsion.

determining the catalyst

Given an exam question, would we be told in the problem what would be the catalyst in a reaction or would we have to determine that ourselves? And if we do have to determine that ourselves, how would we go about determining that? I'm still a bit confused from lecture how that's determined and in how...

RXN rate graph of zero order

In lecture, Professor Lavelle stated that a zero order reaction will be the only time the slope on a graph will be straight. I'm confused because for the graphs in the course reader for 1st and 2nd order reactions, the slopes of those graphs are linear as well, or does it have to do with the fact th...

I asked the guy sitting next to me if he had any Sodium Hypobromite…

He said NaBrO

Boltzmann equation

In the course reader, the lnW in the Boltzmann equation is said to be statistical and that in there being a large error, then it would result in a small error in the thermodynamic property, S. I'm not entirely sure what the statistical aspect of this equation means or represents.

affect of multiple lone pairs on the central atom

I understand how having a single lone pair affects the molecular shape of a molecule, but how does having multiple lone pairs on the central atom affect the shape? Do the lone pairs go one side as one electron cloud, or are they one different regions around the central atom?

electron domain geometry vs molecular geometry [ENDORSED]

I was wondering why for certain molecules, electron domain geometry is different from molecular geometry?
