the next step is f2 + cf2ch3' -> cf3ch3 + f'


oh! that makes sense, thank you. i didn't consider this cuz i thought it would just be made in termination with f. and cf2ch3. reacting

yeah doesn't have hexane hexane was listed in the question or did i go mad


c6h14 is hexane?

You balanced it wrong, the catalutic converter, its no+co=1/2n2+co2

Mark Scheme always allows multiple. So we are both right.

Just counted, I think i lost about 10 if I'm deducting marks for the whole question and no working out marks. I'll add 5 more marks to it just to make sure :redface: So 15 marks wrong.

Me too :/ Mostly because of weird 1 markers ;_; hopefully being the first year for these exams means lower grade boundaries. I think a lot of people made stupid mistakes overall mostly because of time

Ye think thats correct, I took the risk and only learned the two the put down :frown:
"-Graph- I drew it lower and slower because there's fewer moles of reactants."

Lower but not slower, faster because there was a greater concentration in the second mixture

I feel like 64 is a bit high. Even though this exam didn't feel too difficult it was still relatively/slightly harder than previous years and we are the first year to do this exam, with no people resitting and the addition of multiple choice + practicals.. so i'm gonna say maybe 60-62 for an A in this and around 58 ish for an A in the other paper.

How are our overall grades determined? Do they total our marks out of 160?
Also was the honeycomb question 1 or 2 marks?

Apparently it is not by UMS and by raw marks. And examiner will decide which grade is going to be an A*. Check the other thread someone posted a link. Also it was a suggest question so 1 mark I believe.
