For industrial chemistry, is it ok to use square root and keep the coefficient of that molecule as a fraction?

What did u guys get for that multiple choice question with the concentration against time graph where u had to pick what equation it was (From memory i picked d)

 

[NinjaDatHSC]

Yeah same, i found industrial chem hard with that contstant question, what did everyone get for that?

I got something much smaller than the actually number (I think 2 or something close to that?) So I said since there only one equilibrium constant value for a certain temperature, it can't be at equilibrium and it is still moving in the forwards reaction

It used to be uploaded pretty quickly like same day as the exam on sites, but NESA blocked them from doing that this year (something about copyright)

Damn, any non-legit copies floating around?

Did anyone get like 5 c's (for the last five questions) in a row for MC or am I just fucked?

It can sometimes give you a different answer but is technically still correct to that equation with different molar ratios (I guess depends on how they mark)

yeah everyone's getting like 2.84 or smth meanwhile i got like 12. something omfg thought industrial was easy til now

Nope, looks like just have to wait till Friday (nesa releases it like two days after the exam)

Did anyone know how to do the equilibrium constant thing in industrial, i found that so hard idek if i did it right.

I found the paper to be easier than previous years tbh, they were really nice with the 4 and 7 markers, most calculations in section 1 were easy.

Has uploaded a copy of the paper yet?

atar notes always uploads answers to exams it should be up in a couple of hours

I got a number around 3. Idk if its right tho, but definitely a number much smaller than the original 12.1 value

 

[lilrose]

Are there any calculation questions anyone particularly wants the worked solutions to?

The industrial 4 marker on equilibrium constants, the answer i got was so far off I'm not sure if it was right

 

[zeee1999]

what did you guys do for the first question for industrial i completely forgot how to do it

Same i just did the opposite of esterification but replaced one of the OHs with the Na ion i think i did it for the acetate or something like that i can't remember

 

[NinjaDatHSC]

Lol i think i'm stupid, but was question 1 A or D. I put A cause i thought a burette was more accurate to transfer a quantity than a measuring cylinder which is more accurate to measure a quantity?

i put down D becasue I thought a measuring cylinder would be more practical, when I saw the question I though they would've put a pipette or something

WHO GOT Kc = 8.4?!?! (industrial chem)

 

[NinjaDatHSC]

WHO GOT Kc = 8.4?!?! (industrial chem)

Got 2.89 but perhaps i was wrong to leave the half there

 

[Snowflek]

Got 2.89 but perhaps i was wrong to leave the half there

Yeah i got 2.89 when i left the half, but i hate dealing with half so i changed it to 2:1:2 and got 8.4

ayyyyy brother

I forgot to put glycerol I think its part of it FML!!!
