Chem Lab C

Masterhat, if you knew it was first order then you already knew the rate law so you did no have to determine it, or am understanding wrong?

No, pseudo-first order allows you to determine the rate by doing the initial concentration of the limiting reagent / time. Then you can plug this back in for the initial rate to determine the appropriate rate constant and exponents.

(I'm being sarcastic) We drew pictures of elk and at the top we wrote that we like the judge's beard and they're our best friends. Lol. The funny thing is we didn't get last. Our team ended up getting 3rd over all which is cool though. And there were a lot of really smart teams there.

I've gotten this exact strategy (often with "Go IU!" or "We love Indiana!" or "I <3 Chemistry!") on a handful of chem lab exams but never in other events - and when I ran designer genes I definitely had a few teams that could do virtually nothing, but were far less excited about it. My theory: goggles make people feel good.

Chem lab was AWESOME at Indiana this year. People did so well!!! I was really floored.

Now that your event supervision is over, can you share with us some of your ideas for possible labs that you described above as difficult?

If there is an equation involving reactants/products in both the gas and ionic (aqueous) phase, how would the equilibrium expression be written?

Eh, you may need to plug stuff into the solubility equation then the equilibrium equation.

[quizbowl]

so is next year still kinetics and aqueous solutions?

My bet is it will be, it was only in its first year this year. Barring some massive problems we don't know about, it will be the same next year.

Starpug, I would like to congratulate you and the rest of your team on going to nationals 15 years in a row! My school has only made it to nationals once. Good job!

[quizbowl]

lucky, your school has actually gone to nationals...

Don't grumble- Move!

naah, i like it here.
and i think long island should just secede and make its own state - then we can send two teams, namely WM and Syosset. or at least make long island a separate region; we alone have like 130 teams at least. maybe like north cal and south cal?

Meh having a separate region doesn't make things necessarily easier. California still only sends 2 teams for each division. 1 from Div B and C from North Cal and same for South Cal.

O.o reading this thread makes me feel... overhwelmed. I'm signing up for this next year, but now I'm not sure if i should study my inorganic or organic books. help?
