@Kat2016 The lower score will be disregarded.
I want more people to send potential curves! I think the test was easy so the curve will suck. What do you guys think
reaction mechanism definitely is changed by a catalyst. It provides an alternative route (with less activation energy). It may not be in the rate law, but the series of steps (mechanism) will be different because it’s a DIFFERENT ROUTE. Just saying.
As for curve… I’m hoping it’ll be 79 and above to be 800. Online conversions are probably just rough estimates, and this test seems like it was a bit tricky so hopefully the curve is better than the estimates online. Curves are usually tailored to specific tests, so I guess we’ll see on May 21st.
I’m going to need a curve greater than 78 to get me an 800, agh, retake.
what score is two wrong? 
probably 800 if you didn’t get anything else wrong 
Hey guys, there was a question in the TTCE section which was something like this: “If you mix two solutions and they don’t react, the system is in equilibrium”. What did you guys think was the right answer?
The color change one? Think it was FT, but don’t really recall what the second part said.
@tcdcollege that statement is false, but i don’t remember the second half
Anyone remember the question about the helium balloon. Everyone I asked said the answer was the thing about pressure but I thought it said that pressure came from hitting the inner walls and other particles which is untrue, but I could’ve just been wrong.
I think that one was all the He atoms had the same kinetiv energy
Pressure does come from molecules hitting the walls though.
But they don’t. They have the same average
Yup, that’s why there is a KE distribution graph, because all molecules are all different speeds just have the save average at the same temp.
Can someone tell me the best way to prepare for the next Sat chem in june? What should i focus on most? Which guide should i use?
Agreed, not a huge fan of that section. Everything else wasn’t too bad assuming I didn’t make silly mistakes.
What was the answer to that ‘Lithium, sodium and potassium have similar chemical properties’ question in TTCE section?
@baller55 The second part said that “At equilibrium, all change has stopped. Even at the molecular level” This is false because equilibrium can be dynamic
@ros12122 Wasn’t that one of the multiple choice questions? I remember that there was a questions about kinetic energy distribution.
Is it worth retaking this subject test if you think you’re going to get around a 770-780? Barron’s Practice test put me above 780 but somehow I did worse on the actual one. I would have to sign up for the June one before I get my results, which is sort of betting on getting a bad score.
No. Spend the additional time fine-tuning your essays.
