Unit 4 = small

[vexx]

Ahh... if you've got your textbook with you, help me with pg 294 q 22a

22 a?
if you are taking a certain value off one side (value 'x' which is the amount that moved to the other side of the rection) you can assume that this is the amount that is added to the other side.
they abbreviated it to HPr--> Pr- + H30+
Since it's 1:1 the moles are the same.
so in each of those boxes is just 'x'.

yeah it definitely seems a lot shorter just by flicking through.
I use chem dimensions and ive done the first two chapters and plan to do the third of four chapters, thus finishing most AOS1 in the next few days.

So far ive covered the enthalpy graphs, collision theory and all that jazz, and the initial bits of equilibrium including le chatlier's stuff, equilibrium constants etc.

I've yet to cover acid-base equilibria and the case study, which i wont do because i dont know what chemical we are doing, i might have a quick read though.

But yes, overall there hasnt been much theory so far and what there is, is quite easy to comprehend. the maths is pretty easy as well. I could perhaps see myself getting confused with the effects of pressure, temp etc. on equilibrium and its constant though....

More Calculations and Less theory which is why some ppl find unit 4 easier.

woooooo caculations!

If unit 4 is as big as unit 3, then EVERYONE would fail year 12.

I'm liking unit 4, easy to understand.

There is so many tricks... like how they ask how does the value of equilibrium constant indicate about the rate of this chemical reaction...

immediately i think that it is above 10000 so fast rate.

when in fact the answer is "it has nothing to do with the rate"

trick question! so gay

Really? I found unit 4 far more challenging than unit 3. Maybe I'm just...special...like that though

yeahh i did a couple of questions that i was tricked by what exactly to do; especially involving calorimetry questions. everything else is fairly simple, probably the other most tricky i found was electrolysis.
i have so much time to remove tricks so really the course is definitely fine with me xD.. i prefer unit 3 though as organic chemistry was fun!
