What is the Ka, and how do you find it? We don’t have the equilibrium concentrations?

does it even matter anymore
its not like you're gonna touch this subject ever again (unless tutoring people)

guys am i gonna lose marks on q26 for doing a line graph instead of a column graph (looking at catalysts sols rn)

What would a 72 align to this year are guesses?

bro this chat has made me doubt my ability more uhhhhh

It doesn't change KEQ because KEQ is only changed by Temperature.
In the system however it is still dynamic equilibrium, by adding Argon it increases the pressure of the system and causes it to shift towards the right.

adding an inert gas does not affect the equilibrium.

conquer is worse

where'd you guys get solutions for?

I do not recommend looking at the solutions now. Unless you've finished your hscs, looking at this is pointless when you have other subjects to study for. We have no official solutions and there's still a lot of discussion as to what the solutions are. no one can know for certain.

nah you do have the equilibrium concentrations cause you know the pH initially so you can figure out how much acetic acid there is and how much acetate there is

Yeah I calculated pKa = 4.8 by using ice tables

I already finished last year, I just like keeping my mind sharp and yeah I tutor people

Oh I assumed you were 2025
my bad
makes sense

hopefully an 80

I swear they took out all the easy questions that they normally have like combustion and fermentation. To me the last question was a lot easier than some other ones, the test seemed to be more tricky than past years where the only tricky question was the final one ie q39 on 2024 which was almost impossible

was this the qn ab find the ka using the graph?

At least its done
i dont see any point in talking about this anymore

Ok I’ll go goon

Ok I’ll go goon

good idea

 

[C2H6O]

I think they’re talking about the multi

No question 19, finding Ka was not necessary though

Jeez I got fucking cooked
Looking like 88-90ish raw. completely lost a couple questions
