But seriously though, I’m the only one that read: Catalysts aren’t used up because they don’t affect the reaction mechanism?
I can’t even remember the question lol, all I remember is that I thought to myself that catalysts don’t affect the mechanism, but as to whether it was written like that, idk.
Also, I can’t remember if this was on my practice test last night (too lazy to check), or if it was on the actual test. It had to do with molecules colliding with the right size, does anyone else remember more about this? I think it was a I, II, III question type.
A catalyst works by providing a different route, with lower Ea, for the reaction
Isnt the route still the same? It just happens more quickly since the products are more likely to have sufficient energy to overcome the Ea
This is exactly how I read the question too but now I’m doubting myself
What would this test’s difficulty be? From a rank of 1-10. What’s ur opinion?
^10 being as hard as the chem olympiad test, 1 being easy peasy
A solid 7
does anyone remember the KNO3 and CaCl2 question on the true and false
Oh yeah it was asking something about freezing point? Something similar?
CaCl2 has a higher freezing point than KNO3 (false) because CaCl2 will dissociate into 3 ions while KNO3 dissociates into fewer ions (True). I don’t remember how the second statement is worded, but it’s something similar to that.
And what about the catalyst one? I was confident that it would be T,T,CE but it seems like a lot of people put T,F…
I’m not really familiar with the SAT Chem curves, so what do you guys predict 4-5 wrong on the test would be?
What was the T/F question asking if two solutions were mixed and no color change was observed, then the new solution is at equilibrium? I didn’t think it was necessarily true or false so I put true…
what is the yellow color question everyone is talking about. I dont remember seeing it.
@thesupremebanana I put true too but I’m not sure.
@dallascowboys1
the test flame for what element will produce a yellow flame
- sodium
- strontium
- Lithium
… some other choices. Sodium is the correct one.
What about the phase diagram, where was the critical point and that other thing they asked for (wasn’t the triple point).
@nangkhieu hmmmm I don’t remember getting that question and I never have an issue remembering questions. Was it Matching or MC? Or is it a possibility that I didn’t get that question
It was a multiple choice
@alldaboston The triple point is where the 3 lines intersects ( or you could say where the first line diverges into 2 lines). The critical point is the point on top of the second branch between the liquid and gas phases, I guess.
Do scores come out earlier for subject tests?
